coordinate geometry and nets unit test

1 answer

1. What is the distance formula used in coordinate geometry?

Answer: The distance formula is √((x2 - x1)^2 + (y2 - y1)^2).

2. How are the coordinates of a point denoted in coordinate geometry?

Answer: The coordinates of a point are denoted as (x, y).

3. What is the equation of a line in coordinate geometry?

Answer: The equation of a line in coordinate geometry is typically written in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

4. What is a net in geometry?

Answer: A net is a two-dimensional representation of a three-dimensional figure, showing all the faces of the figure laid out flat.

5. How can you find the surface area of a three-dimensional figure using its net?

Answer: To find the surface area of a three-dimensional figure using its net, you would calculate the area of each face shown on the net and then add them together.

6. What is the difference between a triangular prism and a pyramid?

Answer: A triangular prism has two triangular bases and three rectangular faces, while a pyramid has a polygonal base and triangular faces that meet at a common vertex.

7. How do you find the volume of a three-dimensional figure?

Answer: The volume of a three-dimensional figure can be found by multiplying the area of the base by the height of the figure.

8. What is the relationship between the radius of a circle and its diameter?

Answer: The diameter of a circle is twice the length of its radius. In other words, diameter = 2 x radius.
