When do you use CPCTC in a proof?

What is always in the end of a proof

200

What postulate would prove 2 triangles are congruent using all 3 sides of the triangles?

What is SSS

200

State how the triangles are congruent

AAS

200

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

Are these two congruent?

In the following right triangles ΔABC and ΔPQR , if AB = PR, AC = QR then ΔABC ≡ ΔRPQ .

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)
