Congruent Triangles and CPCTC II

Front

What are congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does CPCTC stand for?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.'

Front

What is the AAS congruence criterion?

Back

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

Front

What is the SAS congruence criterion?

Back

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

Front

What is the ASA congruence criterion?

Back

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

Front

What is the significance of the order in congruence statements?

Back

The order of the vertices in a congruence statement indicates which angles and sides correspond to each other.

Front

What does it mean for angles to be vertical?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are always congruent.

Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

What is the relationship between corresponding parts of congruent triangles?

Back

If two triangles are congruent, then all their corresponding parts (sides and angles) are also congruent.

Front

How can you determine if two triangles are congruent using the SSS criterion?

Back

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