What is the Reflexive Property?

Back

A property stating that any geometric figure is congruent to itself.

Front

What is the Definition of Congruence?

Back

Two figures are congruent if they have the same shape and size.

Front

What is the Definition of a Midpoint?

Back

A point that divides a segment into two equal parts.

Front

What does SAS stand for in triangle congruence?

Back

Side-Angle-Side: If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the triangles are congruent.

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle: If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

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

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side: If all three sides of one triangle are congruent to all three sides of another triangle, the triangles are congruent.

Front

When do you use CPCTC in a proof?

Back

ALWAYS at the end.

Front

How do you know that PS = RQ using SAS?

Back

If two sides and the included angle of triangle PSR are congruent to two sides and the included angle of triangle RQS, then PS = RQ by CPCTC.
