Explain 2 features (properties) of a parallelogram that could be used to prove 2 sides congruent in a triangle congruence proof.

the answer is c.

perimeters = 3√10/5

areas = 90/25

i got it down chief.

a reflection across line m

step-by-step explanation:

the first transformation is a 90 degree rotation counterclockwise around the point g. this gets to image gh'j'k'. when the image gh'j'k' is reflected over the line  m the result is g'h"j"k". the final transformation is a reflection over the line  m.
