Below are sample questions representative of the exercises included on this worksheet and related GEO.43 Midpoints and bisectors skill assessments:

Problem 1Difficulty: Mastery
A line intersects segment AB at point C. Which evidence is enough to prove the line is the perpendicular bisector of AB?
AAC = CB and the line is perpendicular to AB at C
BAC = AB and the line is parallel to AB
CC is near the center of the drawing and the line looks vertical
DThe line crosses AB and passes through point A
Solution & Explanation:To be a perpendicular bisector, the line must pass through the midpoint and be perpendicular to the segment. AC = CB proves C is the midpoint, and the right-angle condition proves perpendicularity.
Problem 2Difficulty: Mastery
Segment CD has endpoints C(-8, 2) and D(4, -10). Which point must a perpendicular bisector of CD pass through?
A(-2, -4)
B(6, -12)
C(-4, -2)
D(12, -8)
Solution & Explanation:A perpendicular bisector must pass through the segment's midpoint. The midpoint of CD is ((-8 + 4)/2, (2 + -10)/2) = (-2, -4).
Problem 3Difficulty: Mastery
On segment PQ, R is the midpoint of PQ and S is the midpoint of RQ. If PR = 3x + 6 and SQ = 15, what is x?
A6
B8
C10
D12
Solution & Explanation:Since S is the midpoint of RQ, RQ = 2(15) = 30. Since R is the midpoint of PQ, PR = RQ = 30. Solve 3x + 6 = 30 to get x = 8.
