Geometry Final Exam Review

Front

What are complementary angles?

Back

Angles that add up to 90°.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect.

Front

What is the Side-Angle-Side (SAS) congruence postulate?

Back

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

What is the Angle-Side-Angle (ASA) congruence postulate?

Back

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 is the Side-Side-Side (SSS) congruence postulate?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

How do you find the missing angle in a triangle?

Back

The sum of the angles in a triangle is always 180°. Subtract the known angles from 180° to find the missing angle.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles that add up to 180°.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always equal to each other.
