Answer with explanation:
CPCTC=Corresponding parts of Congruent triangles
Before using the Reason , C P C TC, we Prove two triangles Congruent.
The two triangles can be proven congruent by four ways:
1. →S S S
2.→S AS
3.→A S A
4.→ A A S
⇒So, if triangles are proven congruent by, S S S, then by Reason C P C T C, then other three corresponding angles we prove congruent.
⇒ If triangles are proven congruent by, S A S, then by Reason C P C T C,other two corresponding angles and one side, we prove congruent.
⇒So, if triangles are proven congruent by, A S A, then by Reason C P C T C, then one corresponding angle and other two corresponding sides , we prove congruent.
⇒So, if triangles are proven congruent by, A A S, then by Reason C P C T C, one corresponding angle and other two corresponding sides ,we prove congruent.
