Semester 1 Geometry CP Review

Front

What is the definition of congruent triangles?

Back

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

Front

What does AAS stand for in triangle congruence?

Back

Angle-Angle-Side; a method to prove triangles are congruent by showing two angles and a non-included side are equal.

Front

What is the ASA criterion for triangle congruence?

Back

Angle-Side-Angle; a method to prove triangles are congruent by showing two angles and the included side are equal.

Front

If m∠1 = 30°, what is m∠3 if they are corresponding angles?

Back

m∠3 = 30°; corresponding angles are equal.

Front

What is the SAS criterion for triangle congruence?

Back

Side-Angle-Side; a method to prove triangles are congruent by showing two sides and the included angle are equal.

Front

What is the sum of the interior angles of a triangle?

Back

180°.

Front

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

Back

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

Front

What is the definition of complementary angles?

Back

Two angles that add up to 90°.

Front

What is the definition of supplementary angles?

Back

Two angles that add up to 180°.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are equal in measure.
