What does cpctc represent and when would you use it?

The definition and representation of CPCTC is written below.

Step-by-step explanation:

CPCTC stands for Corresponding part of congruent triangle are congruent.

That is, If two triangles are congruent then their corresponding parts ( sides or angle) are also congruent.

For example: If there are two triangles ABC and PQR and it is given that \triangle ABC\cong \triangle PQR

Then According to CPCTC, ,   and

While sides , and  .

$649.60

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
