Congruent Triangles Flashcard

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

List the tests for triangle congruence.

Back

SAA (Side-Angle-Angle), SSS (Side-Side-Side), SAS (Side-Angle-Side), HL (Hypotenuse-Leg for right triangles).

Front

Which test is NOT a valid method for proving triangle congruence?

Back

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

Front

What does SAA stand for in triangle congruence?

Back

SAA stands for Side-Angle-Angle, a method to prove triangles congruent.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a method to prove triangles congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a method to prove triangles congruent.

Front

What is the reflexive property in geometry?

Back

The reflexive property states that a geometric figure is congruent to itself.

Front

What is the definition of a midpoint?

Back

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

Front

What is CPCTC?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent.

Front

What is the Hypotenuse-Leg (HL) theorem?

Back

The HL theorem states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.
