What are the four congruent triangle theorems?

Back

1. SSS (Side-Side-Side) Congruence Theorem: If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent. 2. SAS (Side-Angle-Side) Congruence Theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent. 3. ASA (Angle-Side-Angle) Congruence Theorem: If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent. 4. AAS (Angle-Angle-Side) Congruence Theorem: If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, the 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 given by the formula: (n - 2) × 180°.

Front

What is the sum of the exterior angles of any polygon?

Back

The sum of the exterior angles of any polygon is always 360°.

What is the measure of each interior angle of a regular polygon with n sides?

Back

The measure of each interior angle of a regular polygon with n sides is given by the formula: [(n - 2) × 180°] / n.

What is the relationship between interior and exterior angles at each vertex of a polygon?

Back

At each vertex of a polygon, the interior angle and the exterior angle are supplementary, meaning they add up to 180°.
