Question

How would I prove that triangle APK is congruent to triangle RPK?

Answer 1

More information is needed

Explanation:

I would consider myself pretty decent with proofs, but I believe that more information is needed.
We already have one side due to the reflexive postulate (side `PK`), since the whole side is in both triangles. However we would need either:

`AP` and `RK` are parallel

OR angle `APK` and `RKP` are right angles that have an angle bisector.

Otherwise, we would just be making assumptions.
