SSS and SAS Triangle Congruence

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence stating 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.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself. For example, triangle ABC is congruent to triangle ABC.

Front

What is the Definition of Midpoint?

Back

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

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of a transversal and inside two parallel lines. They are congruent.

Front

What is the purpose of the SSS Triangle Congruence theorem?

Back

The SSS Triangle Congruence theorem is used to prove that two triangles are congruent based on the equality of their three corresponding sides.

Front

What is the purpose of the SAS Triangle Congruence theorem?

Back

The SAS Triangle Congruence theorem is used to prove that two triangles are congruent based on the equality of two sides and the included angle.

Front

How can you determine if two triangles are not congruent?

Back

Two triangles are not congruent if their corresponding sides and angles do not match in measure.

Front

What is CPCFC?

Back

CPCFC stands for Corresponding Parts of Congruent Figures are Congruent, which means that if two figures are congruent, then all their corresponding parts are also congruent.

Front

What is the Substitution Property?

Back

The Substitution Property states that if two quantities are equal, one can be substituted for the other in any expression.
