An angle is formed by two rays sharing a common endpoint called the vertex. There are five types of angles: acute angles less than 90 degrees, right angles equal to 90 degrees, obtuse angles greater than 90 but less than 180 degrees, straight angles equal to 180 degrees, and reflex angles greater than 180 degrees. The parts of an angle are the vertex, which is the corner point where the two arms meet, and the two arms, which are the straight sides that form the angle between them.

- 2. What is an Angle? an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
- 3. Types of Angle 1. Acute Angle Acute Angles- an angle that is less than 90°
- 4. 2. Right Angle Right Angle- an angle that is 90° exactly
- 5. 3. Obtuse Angle Obtuse Angle- an angle that is greater than 90° but less than 180°
- 6. 4. Straight Angle Straight Angle- an angle that is 180° exactly
- 7. 5. Reflex Angle Reflex Angle- an angle that is greater than 180°
- 8. Parts of an Angle
- 9. The corner point of an angle is called the vertex And the two straight sides are called arms The angle is the amount of turn between each arm.
- 10. Vertex- typically means a corner or a point where lines meet. Arm- is any of the two straight lines that form the angle
