are these two congruent.
Following the HL theorem, in △ABC and △PQR: BC = QR (congruent hypotenuse)
Thus, y = 13
AC = PQ (congruent legs)
Thus, x = 5.
Therefore, x = 13, y = 5

True or false CPCTC can be used for just sides?
what is false
400
Are the triangles similar? If so, what theorem proves it?
SSS similarity
400
The method used is: 
What is AAS
400
Are these Triangles congruent?
ΔABC and ΔPQR are right triangles
AC = PQ (hypotenuse)
AB = PR (leg) So, triangle ABC and triangle PQR are congruent by the Hypotenuse Leg Theorem.

ASA is a congruence ___________.
What is postulate?
500
prove that △PSR ≅ △PQR.
It is given that △PSR and △PQR are right-angled triangles.
PS = QR (equal legs, given)
PR = PR (equal and common hypotenuse)
Hence, △PSR ≅ △PQR (by HL rule)
