Triangle Congruency

Front

What does SSA stand for in triangle congruency?

Back

SSA stands for Side-Side-Angle, which is NOT a valid shortcut for proving triangles congruent.

Front

What is the HL Congruence Theorem?

Back

The HL Congruence Theorem states that if two right triangles have equal hypotenuses and one pair of equal legs, then the triangles are congruent.

Front

What information is required to prove triangles are congruent using the SSS postulate?

Back

Three sides of one triangle must be equal to the three sides of another triangle.

Front

What does SAS stand for in triangle congruency?

Back

SAS stands for Side-Angle-Side, which is a valid shortcut for proving triangles congruent.

Front

What is the definition of congruent triangles?

Back

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

Front

What is the ASA Congruence Postulate?

Back

The ASA Congruence Postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the AAS Congruence Theorem?

Back

The AAS Congruence Theorem states that 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, then the triangles are congruent.

Front

What is the definition of the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

What is the significance of the included angle in triangle congruency?

Back

The included angle is the angle formed between two sides of a triangle, and it is crucial for certain congruence postulates like SAS.

Front

What does the term 'corresponding parts' refer to in triangle congruency?

Back

Corresponding parts refer to the sides and angles of triangles that are in the same relative position.
