Triangle Congruence Proofs

Front

What is the Reflexive Property of Equality (POE)?

Back

For any segment AB, AB = AB. This property states that any quantity is equal to itself.

Front

What is the statement for step 3 of a triangle congruence proof?

Back

HA=HA, indicating that the angles or segments being compared are equal.

Front

Which of the following is NOT a triangle congruence criteria?

Back

SSA (Side-Side-Angle) is not a valid triangle congruence criterion.

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 Midpoint?

Back

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

Front

What is the Angle-Side-Angle (ASA) congruence criterion?

Back

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

Front

What is the Side-Angle-Side (SAS) congruence criterion?

Back

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

Front

What is the Angle-Angle-Side (AAS) congruence criterion?

Back

If two angles and a 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 purpose of a proof in geometry?

Back

To provide a logical argument that demonstrates the truth of a geometric statement.

Front

What does it mean for angles to be congruent?

Back

Congruent angles have the same measure.
