MOD5 Angles Review

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What does the Triangle Sum Theorem state?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180°.

Front

How do you find the measure of an angle in a triangle if two angles are known?

Back

Subtract the sum of the known angles from 180° to find the measure of the unknown angle.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90°.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180°.

Front

Define linear pair of angles.

Back

A linear pair of angles consists of two adjacent angles formed when two lines intersect. They are supplementary.

Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common vertex and a common side but do not overlap.

Front

How do you identify vertical angles in a diagram?

Back

Vertical angles are located across from each other at the intersection of two lines.

Front

What is the measure of a right angle?

Back

A right angle measures 90°.
