HOW TO IDENTIFY DIFFERENT TYPES OF ANGLES

- Have ONE vertex
- Consist of two rays that meet at a point
- Have perfectly straight lines
- Angles are measured in degrees(°)
- Angles are measured with protractors

- All right angles are exactly 90°
- No right angle can be more or less than 90°
- A right angle always has a box where the lines meet

- All acute angles are less than 90°
- All angles less than 90° are acute
- The vertex is marked by a curved line

- All obtuse angles are more than 90° and less than 180°
- All angles less than 180° and more than 90° are obtuse
- The vertex is marked by a curved line

- All straight angles are exactly 180°
- No straight angle can be more or less than 180°
- It looks sometimes like just a line but it really is an angle

- A reflex angle is always more than 180° and less than 360°
- Any angle less than 360° and more than 180° is a reflex angle
- The curve (called an arc) of a reflex indicates how to measure it
- The arc of a reflex angle will always be more than a half circle

I HOPE YOU LEARNED A LOT!!!!!!!!
