ingrid wants to prove that the diagonals of a parallelogram bisect each other, using the figure below.

which statement and reason should be part of her proof?

a
△qmr≅△smt by asa

b
△qmr≅△tms by asa

c
△qrs≅△sqt by sss

d
△qrs≅△rtq by sss

Option A.

Step-by-step explanation:

Given: QRST is a parallelogram and M is the intersection of diagonals.

We know that opposite sides of a parallelogram are parallel and equal.

In △QMR and △SMT,

   (Alternate interior angles)

       (Definition of parallelogram)

   (Alternate interior angles)

Two corresponding angles and included sides are congruent.

       (ASA postulate)

Hence, the correct option is A.

17,000 is the correct answer.
