Congruent Triangles

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a postulate that states 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 does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a postulate that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

Which triangle congruence method is not valid?

Back

The SSA (Side-Side-Angle) method is not a valid method for proving triangle congruence.

Front

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

Back

The hypotenuse is the side opposite the right angle in a right triangle.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that creates a mirror image of a shape across a line.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the definition of the SSS postulate?

Back

SSS stands for Side-Side-Side, a postulate that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the difference between congruence and similarity in triangles?

Back

Congruence means the triangles are the same size and shape, while similarity means the triangles have the same shape but may be different sizes.

Front

What is the Angle-Angle (AA) similarity postulate?

Back

The AA postulate states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the definition of an included angle in triangle congruence?

Back

An included angle is the angle formed between two sides of a triangle.
