Flashcard CPCTC

Front

What does CPCTC stand for?

Back

Corresponding parts of congruent triangles are congruent.

Front

When can we use the HL Congruence Theorem?

Back

Right Triangles.

Front

What is the SSS Congruence Theorem?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the SAS Congruence Theorem?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the ASA Congruence Theorem?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the definition of congruent triangles?

Back

Triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the HL Congruence Theorem?

Back

If the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Front

What does it mean for triangles to be not congruent?

Back

It means that the triangles do not have the same shape and size; their corresponding sides and angles are not equal.

Front

What is the difference between SSA and other congruence theorems?

Back

SSA does not guarantee triangle congruence; it can lead to ambiguous cases.

Front

Provide an example of when to use the SSS Congruence Theorem.

Back

When you know the lengths of all three sides of two triangles.
