In parallelogram PQRS, diagonals PR and QS intrsect at M. Which is always true?
(1) PR is perpendicular to QS
(2) PM is congruent to RM
(3) PQ is congruent to QR
(4) triangle PMS is congruent to triangle PMQ
4 answers
obviously (2)
But it does not say that M is the midpoint?
One of the fundamental properties of a parallelogram is that its diagonals bisect each other
Oh, I understand. Thank you!
