Justify the last two steps of the proof. given: mn=po and mo=pn prove: mno=pon

The figure of this problem is attached.

Givens:

Now, according to the hypothesis, all three corresponding sides are congruent, that is:

Therefore, the SSS postulate, Side-Side-Side postulate, both triangles are congruent. From this congruence each corresponding pair of angles are equivalent.

y=x

Step-by-step explanation:

When the pentagon is reflected across y=x, all of its points are placed equally distant from the diagonal on one side as they are from the other. This causes the figure to turn 90 degrees instead of flipping like in any of the other reflections. Hope this helps!
