1. Angles are everywhere
Just look around YOU!

2. What is an Angle?

3. An Angles is.. When two lines meet at a point they make an angle
The angle describes how much you have to turn between the two lines.
We can measure ‘how much turn’ an angle has by using units called degrees.
Example: 20° ( 20 degrees)
ANGLE

4. There are different types of angles.
The number of degrees shows how small or big the angle is.
35 °
127 °

5. How would you describe these angles?

6. Acute Angles
An acute angle is smaller than 90°

7. How would you describe these angles?

8. Right Angles
A right angle is exactly 90°

9. How would you describe these angles?

10. Obtuse Angles
An Obtuse angle is larger than 90° but smaller than 180°

11. What does a 180° angle look like?
A 180° angle is a STRAIGHT LINE

12. How would you describe this angle?

13. Reflex Angles
A reflex angle is bigger than 180° but smaller than 360°

14. What does a 360° angle look like?
A 360° angle is ONE whole turn !
¼ of a turn
½ of a turn
1 whole turn
