Question

AB=CD. Point P is the midpoint of AB. Point Q is the midpoint of CD . Point R is the midpoint of . Point S is the midpoint of QD . Which is an invalid relation.
A. Segment QD is congruent to segment AP
B. Segment PB is congruent to segment CQ
C. Segment QD is congruent to segment PB
D. Segment AP is congruent to segment PQ
E. Segment CQ is congruent to segment AP
Because point R is the midpoint of AP and point S is the midpoint of QD , we can conclude that...
A. Segment RP is congruent to segment CS
B. Segment RB is congruent to segment CS
C. Segment RB is congruent to segment SD

Answer 1

D. Segment AR is congruent to segment CS
E. Segment RB is congruent to segment QS
