6 Congruent Triangle Theorems, Int/Ext Angles of Polygons, Rates

Front

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.

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time.

Front

If you travel at a constant speed of 60 miles per hour for 4 hours, how far do you travel?

Back

240 miles.

Front

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°.

Front

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.

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 does the SSS postulate state about triangle congruence?

Back

The SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Front

What does the AAS postulate state about triangle congruence?

Back

The AAS (Angle-Angle-Side) postulate 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 two triangles are congruent.

Front

If a triangle has angles measuring 30° and 60°, what is the measure of the third angle?

Back

The third angle measures 90°.
