Identify Angles

What is an angle?

• An angle is formed by two rays that share a common endpoint, called the vertex.

• An angle is a measure of the distance between two points.

• An angle is a type of polygon with three sides.

• An angle is a straight line that extends infinitely in both directions.

How do you identify an acute angle?
