Types of Angles

Angles

• An angle is a figure that is formed by two rays that meet at the same endpoint.

• The endpoint that they share is called a vertex.

Types of angles

• RIGHT ANGLE - Exactly 90 degrees

• ACUTE ANGLE - Less than 90 degrees

• OBTUSE ANGLE - Greater than 90 degrees but less than 180 degrees

• STRAIGHT ANGLE - Exactly 180 degrees; makes a straight line
