I can help with all of these, but I can’t see the images in your quiz. Could you either (a) attach the images or (b) type the equations/angle/side values shown in each image? With the images I can give exact multiple-choice answers.
Meanwhile, here are the parts I can answer or explain without the images and some general methods you can use to finish the image-based questions:
1) Which equations could be used to calculate slope?
- Correct forms are any equivalent to m = (y2 − y1) / (x2 − x1). Also “rise/run” or m = Δy/Δx. (Do NOT use (x2 − x1)/(y2 − y1).)
2) What must be true for two lines to be parallel?
- The slopes of the lines must be the same.
3) Which equation would be perpendicular to y = 2x + 3?
- A perpendicular line must have slope = −1/2 (negative reciprocal of 2). So pick the option whose slope is −1/2 (any y = −(1/2)x + b).
4) (Image needed) — I can identify the angle relationship once I can see the picture.
5) If an angle is bisected by a line segment, what must be true of the two angles?
- They must be equal (congruent).
6) (Image needed) — I can identify the theorem once I can see the picture. Hints:
- If the picture shows a segment split into two adjacent segments whose lengths add to the whole, that’s the Segment Addition Postulate.
- If it’s showing an angle’s measures adding to 180 it might be about supplementary angles or Triangle Sum for triangles, etc.
7) Which theorem says base angles of an isosceles triangle are congruent?
- The Base Angles Theorem (in an isosceles triangle the two base angles are congruent).
8–14) (Images needed) — I need the actual diagrams/values to pick the numeric answer. Here are the typical facts to use for parallelograms/rectangles:
- Parallelogram facts: opposite sides are congruent, opposite angles are congruent, adjacent angles are supplementary (sum to 180°), diagonals bisect each other.
- Rectangle facts: all angles 90°, opposite sides congruent, diagonals are equal in length (so diagonal AC ≅ diagonal BD).
Use those to set up equations. If you paste each diagram’s numbers I’ll compute x, y, or the congruent segment.
15) Define “perpendicular bisector” and what it creates (you can use this directly):
- A perpendicular bisector of a segment is a line (or segment) that both (1) cuts the segment into two equal parts (bisects it) and (2) meets the segment at a right angle (is perpendicular to it).
- A perpendicular bisector creates two congruent segments (the two halves of the original segment) and a right angle at the point of intersection. If used in triangle geometry, any point on the perpendicular bisector is equidistant from the two endpoints of the bisected segment, so it can create congruent segments from that point to each endpoint and produce congruent base angles in some constructions.
16) Relationships in parallel lines cut by a transversal (example answer you can adapt to your picture):
- Alternate interior angles: equal (congruent). They are nonadjacent angles on opposite sides of the transversal that lie between the two parallel lines.
- Corresponding angles: equal (congruent). One interior and one exterior angle in matching positions.
- Consecutive (same-side) interior angles: supplementary (sum to 180°).
Explain each by noting the parallel lines and the transversal and using the appropriate theorem name.
17) Two ways to prove a quadrilateral is a parallelogram (choose any two):
- Show both pairs of opposite sides are parallel. If both pairs of opposite sides are parallel, the quadrilateral is a parallelogram.
- Show both pairs of opposite sides are equal in length. If both pairs of opposite sides are congruent, the quadrilateral is a parallelogram.
Other valid methods: show diagonals bisect each other; show one pair of opposite sides is both parallel and equal.
