Triangle Congruence

Front

What is the Reflexive Property of Equality?

Back

The Reflexive Property of Equality states that any quantity is equal to itself, expressed as A = A.

Front

What is the definition of a midpoint?

Back

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

Front

If two triangles are congruent, what can be said about their corresponding sides?

Back

If triangle BCDE is congruent to triangle OPQR, then the corresponding sides are equal, meaning DE = QR.

Front

What is the Symmetric Property of Congruence?

Back

The Symmetric Property of Congruence states that if one figure is congruent to another, then the second figure is congruent to the first.

Front

What does it mean for angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the Transitive Property of Equality?

Back

The Transitive Property of Equality states that if A = B and B = C, then A = C.

Front

What is the definition of congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size.

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

The AA criterion states that if two angles of one triangle are congruent to two angles of another triangle, the triangles are similar.

Front

What is the Side-Side-Side (SSS) criterion for triangle congruence?

Back

The SSS criterion states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

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

Back

The SAS criterion states that 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.
