Front

Define an angle.

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex).

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What is a linear pair of angles?

Back

A linear pair of angles is a pair of adjacent angles formed when two lines intersect, and they are supplementary.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the measure of a straight angle?

Back

A straight angle measures 180 degrees.

Front

What is a vertical angle?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are always equal.

Front

How do you name an angle?

Back

An angle can be named using its vertex and a point on each ray, e.g., ∠ABC.

Front

What is the symbol for angle?

Back

The symbol for angle is '∠'.
