I can finish all of these, but several questions rely on pictures you didn’t include. Below I answer the ones that don’t need the images and give general instructions or templates you can use for the picture questions. If you upload the missing images (or type the equations/angle measures shown), I’ll give the specific multiple-choice answers.
Answers I can give now
1) Which equation can be used to calculate slope?
- m = (y2 − y1) / (x2 − x1) (also described as rise/run)
2) What must be true for two lines to be parallel?
- The slopes of the lines must be the same.
3) A line is y = 2x + 3. Which equation would be perpendicular?
- A perpendicular line must have slope = −1/2. So pick the equation whose slope is −1/2 (e.g., y = −(1/2)x + b).
5) If an angle is bisected by a line segment, what must be true of the two resulting angles?
- They must be equal (congruent).
7) Which theorem says the base angles of an isosceles triangle are congruent?
- Base Angles Theorem.
15) Explain “perpendicular bisector” and what it creates (3 points — sample answer you can use)
- A perpendicular bisector of a segment is a line (or line segment) that meets the original segment at its midpoint and forms a right angle (90°) with it. It therefore divides the original segment into two congruent segments and creates right angles at the point of intersection. In triangle geometry, a perpendicular bisector of a side gives points on that line that are equidistant from the two endpoints of the side; perpendicular bisectors of the sides of a triangle meet at the circumcenter.
16) Relationships between angle pairs when two parallel lines are cut by a transversal (3 points — general template)
- Alternate interior angles: The pairs on opposite sides of the transversal and inside the two parallel lines are congruent. (Example: ∠A and ∠B are alternate interior → ∠A = ∠B.)
- Corresponding angles: An angle in one line and the matching position angle on the other line are congruent. (Example: ∠C corresponding to ∠D → ∠C = ∠D.)
- Consecutive (same-side) interior angles: The two interior angles on the same side of the transversal are supplementary (sum to 180°).
- Alternate exterior angles: The pairs outside the two lines and on opposite sides of the transversal are congruent.
(If you upload the picture I’ll name specific angle pairs from that diagram and explain why using these terms.)
17) Two ways to prove a quadrilateral is a parallelogram (3 points — provide at least two)
Use any two of these valid methods and justify why they prove the figure is a parallelogram:
- Show both pairs of opposite sides are parallel. If opposite sides are parallel, the quadrilateral is a parallelogram by definition.
- Show both pairs of opposite sides are congruent (equal in length). If both pairs of opposite sides are equal, the quadrilateral is a parallelogram.
- Show one pair of opposite sides is both parallel and congruent. That is sufficient to prove the quadrilateral is a parallelogram.
- Show diagonals bisect each other (they cut each other into two equal parts). If diagonals bisect each other, the quadrilateral is a parallelogram.
Questions I need images or more info for (please upload or type the text shown)
- Q1: (if there were multiple formula images — I already gave the correct formula m = (y2 − y1)/(x2 − x1))
- Q3: If you want me to pick one of the listed options, upload the full list or images.
- Q4: Need the picture of the angles to identify whether they are alternate interior, exterior, corresponding, or consecutive interior.
- Q6: Need the picture to identify which theorem is represented.
- Q8, Q9, Q10, Q11, Q12, Q13, Q14: All need the figures and/or the algebraic angle/segment expressions shown in the images.
If you upload the missing images (or type the angle measures/equations from them), I’ll finish every multiple-choice question and show the algebra or reasoning used.
