To classify triangle ABC, we need to examine its sides and angles.
Given the coordinates, we can find the lengths of the sides using the distance formula:
AB = √((x2 - x1)^2 + (y2 - y1)^2)
BC = √((x3 - x2)^2 + (y3 - y2)^2)
CA = √((x1 - x3)^2 + (y1 - y3)^2)
Using the provided coordinates, we can calculate the lengths of the sides as follows:
AB = √((2 - 3)^2 + (-5 - (-2))^2) = √(1^2 + (-3)^2) = √(1 + 9) = √10
BC = √((4 - 2)^2 + (-5 - (-5))^2) = √(2^2 + 0^2) = √(4 + 0) = 2
CA = √((3 - 4)^2 + (-2 - (-5))^2) = √((-1)^2 + 3^2) = √(1 + 9) = √10
Now, let's analyze the angles:
Angle A can be found using the Law of Cosines:
cos(A) = (BC^2 + CA^2 - AB^2) / (2 * BC * CA)
cos(A) = (2^2 + √10^2 - √10^2) / (2 * 2 * √10)
cos(A) = (4 + 10 - 10) / (4 * √10)
cos(A) = 4 / (4 * √10)
cos(A) = 1 / √10
A = cos^(-1)(1 / √10)
Angle B can be found using the Law of Sines:
sin(B) = (AB * sin(A)) / BC
sin(B) = (√10 * sin(A)) / 2
B = sin^(-1)((√10 * sin(A)) / 2)
Angle C = 180° - A - B
Now, we can classify the type of triangle based on these values:
- If all three sides have the same length and all three angles are equal, the triangle is equilateral.
- If two sides have the same length and the angles opposite those sides are equal, the triangle is isosceles.
- If none of the sides have the same length and none of the angles are equal, the triangle is scalene.
- If two angles are equal, the triangle is isosceles (this is not applicable in this case since we don't know the angles yet).
- If all angles are less than 90° (acute angles), the triangle is acute.
- If one angle is exactly 90° (right angle), the triangle is right.
- If one angle is greater than 90° (obtuse angle), the triangle is obtuse.
Based on the information provided, we have calculated the side lengths and can use the angles to further classify the triangle. However, to fully classify the triangle, we would need to know the values of angle A, angle B, and angle C.
Given the coordinates, we can find the lengths of the sides using the distance formula:
AB = √((x2 - x1)^2 + (y2 - y1)^2)
BC = √((x3 - x2)^2 + (y3 - y2)^2)
CA = √((x1 - x3)^2 + (y1 - y3)^2)
Using the provided coordinates, we can calculate the lengths of the sides as follows:
AB = √((2 - 3)^2 + (-5 - (-2))^2) = √(1^2 + (-3)^2) = √(1 + 9) = √10
BC = √((4 - 2)^2 + (-5 - (-5))^2) = √(2^2 + 0^2) = √(4 + 0) = 2
CA = √((3 - 4)^2 + (-2 - (-5))^2) = √((-1)^2 + 3^2) = √(1 + 9) = √10
Now, let's analyze the angles:
Angle A can be found using the Law of Cosines:
cos(A) = (BC^2 + CA^2 - AB^2) / (2 * BC * CA)
cos(A) = (2^2 + √10^2 - √10^2) / (2 * 2 * √10)
cos(A) = (4 + 10 - 10) / (4 * √10)
cos(A) = 4 / (4 * √10)
cos(A) = 1 / √10
A = cos^(-1)(1 / √10)
Angle B can be found using the Law of Sines:
sin(B) = (AB * sin(A)) / BC
sin(B) = (√10 * sin(A)) / 2
B = sin^(-1)((√10 * sin(A)) / 2)
Angle C = 180° - A - B
Now, we can classify the type of triangle based on these values:
- If all three sides have the same length and all three angles are equal, the triangle is equilateral.
- If two sides have the same length and the angles opposite those sides are equal, the triangle is isosceles.
- If none of the sides have the same length and none of the angles are equal, the triangle is scalene.

As all three sides have different lengths, the triangle is classified as scalene. Therefore, the correct response is:
It is a scalene triangle.

To make triangle ABC isosceles, we need to have two sides of equal length. In this case, the two sides that are already given are AB and AC. To make AB and AC equal in length, we need point C to be the midpoint between points A and B.
Using the midpoint formula, we can calculate the coordinates of the midpoint:
Cx = (Ax + Bx) / 2
Cy = (Ay + By) / 2
Plugging in the values:
Cx = (2 + 3) / 2 = 5/2 = 2.5
Cy = (4 + 6) / 2 = 10/2 = 5
Therefore, the coordinates of point C that make triangle ABC isosceles are C(2.5, 5). The correct response is:
C(2.5, 5)

To determine if quadrilateral QRST is a parallelogram, we need to check if opposite sides are parallel. We can find the slopes of the sides QR, RS, ST, and TQ by using the formula (y2 - y1) / (x2 - x1).
The slope of QR = (8 - 5) / (2 - (-1)) = 3/3 = 1.
The slope of RS = (4 - 8) / (4 - 2) = -4/2 = -2.
The slope of ST = (1 - 4) / (1 - 4) = -3/(-3) = 1.
The slope of TQ = (5 - 1) / (-1 - 4) = 4/(-5) = -4/5.
Since the opposite sides QR and ST have the same slope of 1, this indicates they are parallel. Additionally, the opposite sides RS and TQ have the same slope of -2/5, indicating they are parallel.
Now, let's solve for x to determine the measure of angle R. Given that angle Q is 108°, angle R must be equal to 108 - 2x. Since opposite angles of a parallelogram are congruent, angle Q and angle S must be congruent, and angle R and angle T must be congruent.
So, 108 - 2x = 108.
Subtracting 108 from both sides, we have -2x = 0.
Dividing by -2, we find x = 0.
Therefore, quadrilateral QRST is a parallelogram, and x = 0.
The slope of QR = (8 - 5) / (2 - (-1)) = 3/3 = 1.
The slope of RS = (4 - 8) / (4 - 2) = -4/2 = -2.
The slope of ST = (1 - 4) / (1 - 4) = -3/(-3) = 1.
The slope of TQ = (5 - 1) / (-1 - 4) = 4/(-5) = -4/5.
Since the opposite sides QR and ST have the same slope of 1, this indicates they are parallel. Additionally, the opposite sides RS and TQ have the same slope of -2/5, indicating they are parallel.
Now, let's solve for x to determine the measure of angle R. Given that angle Q is 108°, angle R must be equal to 108 - 2x. Since opposite angles of a parallelogram are congruent, angle Q and angle S must be congruent, and angle R and angle T must be congruent.
So, 108 - 2x = 108.
Subtracting 108 from both sides, we have -2x = 0.
Dividing by -2, we find x = 0.
Therefore, quadrilateral QRST is a parallelogram, and x = 0.

To find the perimeter of the triangle, Nathan needs to calculate the sum of the lengths of its three sides. This can be done by using the distance formula which states that the distance between two points (x1, y1) and (x2, y2) is given by:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Here are the steps Nathan needs to follow to find the perimeter:
1. Find the distance between points (1, 5) and (4, 1):
Distance1 = sqrt((4 - 1)^2 + (1 - 5)^2) = sqrt(3^2 + (-4)^2) = sqrt(9 + 16) = sqrt(25) = 5
2. Find the distance between points (4, 1) and (-4, -5):
Distance2 = sqrt((-4 - 4)^2 + (-5 - 1)^2) = sqrt((-8)^2 + (-6)^2) = sqrt(64 + 36) = sqrt(100) = 10
3. Find the distance between points (-4, -5) and (1, 5):
Distance3 = sqrt((1 - (-4))^2 + (5 - (-5))^2) = sqrt(5^2 + 10^2) = sqrt(25 + 100) = sqrt(125) = 5sqrt(5)
4. Add the three distances together to find the perimeter:
Perimeter = Distance1 + Distance2 + Distance3 = 5 + 10 + 5sqrt(5)
To round to the nearest tenth, we have:
Perimeter ≈ 5 + 10 + 5.0 ≈ 20.0
Therefore, the perimeter of the triangle, rounded to the nearest tenth of a unit, is 20.0 units.
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Here are the steps Nathan needs to follow to find the perimeter:
1. Find the distance between points (1, 5) and (4, 1):
Distance1 = sqrt((4 - 1)^2 + (1 - 5)^2) = sqrt(3^2 + (-4)^2) = sqrt(9 + 16) = sqrt(25) = 5
2. Find the distance between points (4, 1) and (-4, -5):
Distance2 = sqrt((-4 - 4)^2 + (-5 - 1)^2) = sqrt((-8)^2 + (-6)^2) = sqrt(64 + 36) = sqrt(100) = 10
3. Find the distance between points (-4, -5) and (1, 5):
Distance3 = sqrt((1 - (-4))^2 + (5 - (-5))^2) = sqrt(5^2 + 10^2) = sqrt(25 + 100) = sqrt(125) = 5sqrt(5)
4. Add the three distances together to find the perimeter:
Perimeter = Distance1 + Distance2 + Distance3 = 5 + 10 + 5sqrt(5)
To round to the nearest tenth, we have:
Perimeter ≈ 5 + 10 + 5.0 ≈ 20.0
Therefore, the perimeter of the triangle, rounded to the nearest tenth of a unit, is 20.0 units.

To find the area of the acute triangle, Amaury can use the method of drawing a rectangle circumscribing the triangle and forming right triangles. Here are the steps Amaury can follow:
1. Plot the coordinates of the triangle's vertices on the coordinate grid: A(-3, 5), B(3, 7), and C(2, 3).
2. Determine the length and height of the circumscribing rectangle:
- The length of the rectangle is found by subtracting the x-coordinate of point A from the x-coordinate of point B: 3 - (-3) = 6.
- The height of the rectangle is found by subtracting the y-coordinate of point C from the y-coordinate of point B: 7 - 3 = 4.
3. Calculate the area of the rectangle by multiplying the length and height: 6 * 4 = 24 square units.
4. Divide the area of the rectangle by 2 to find the area of the acute triangle. This is because the circumscribing rectangle contains two copies of the triangle (one facing up and one facing down) with the same area: 24 / 2 = 12 square units.
Therefore, the area of the acute triangle, formed by points A(-3, 5), B(3, 7), and C(2, 3), is 12 square units.
