What does the SAS postulate state about triangle congruence?

Back

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

What is the sum of the interior angles of a polygon with n sides?

Back

The sum of the interior angles of a polygon with n sides is (n - 2) × 180°.

How do you find the measure of an exterior angle of a polygon?

Back

The measure of an exterior angle of a polygon is equal to the sum of the measures of the two non-adjacent interior angles.

Front

What is the relationship between the interior and exterior angles of a triangle?

Back

The sum of the measures of the interior angles of a triangle is 180°, and each exterior angle is equal to the sum of the two opposite interior angles.

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.
