Iwill give in quadrilateral abcd, diagonals ac and bd bisect one another: what statement is used to prove that quadrilateral abcd is a parallelogram? (a) angles bad and adc are congruent. (b) corresponding angles bcd and cda are supplementary. (c) sides cd and da are congruent. (d) triangles bpa and dpc are congruent.

In order to prove that this quadrilateral is a parallelogram, we need to get the opposite sides to be parallel.

The answer would be D because it shows 2 triangles to be equal. If they are equal then they must have corresponding sides.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

ab will be equal to
