Triangle congruence Proofs

Front

What are the triangle congruence criteria?

Back

The triangle congruence criteria are: SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and HL (Hypotenuse-Leg) for right triangles.

Front

Which triangle congruence criterion is NOT valid?

Back

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

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, which means 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 is the definition of AAS?

Back

AAS stands for Angle-Angle-Side, which means 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 is the Vertical Angle Theorem?

Back

The Vertical Angle Theorem states that vertical angles are congruent.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

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 Midpoint Theorem?

Back

The Midpoint Theorem states that if a point is the midpoint of a segment, then it divides the segment into two equal parts.

Front

What does CPCTC stand for?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent.

Front

What is the definition of a bisector?

Back

A bisector is a line or segment that divides an angle or segment into two equal parts.
