Congruent Triangles

How do you identify if two triangles are ≅ by using SSS?

• If only one △ has all congruent sides

• If the △s have only one side that is ≅ to each other

• If all three sides of one △ are equivalent to the other △

• If each △ has the same amount of sides but different lengths

What does CPCTC stand for?
