2. What is an angle?

3. Angle Defined:
The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet

4. Where can we find angles?

5. Different types of angles
There are many different types of angles, some include: - acute
- right
- obtuse
- straight
- reflex

6. Acute Angles
An acute angle is less than 90 degrees but more than 0 degrees.

7. Right Angles
A right angle is an angle of 90°, as in a corner of a square.

8. Obtuse Angle
An obtuse angle is an angle between 90 and 180 degrees

9. Straight Angle
A straight angle is an angle of 180 degrees, a straight line.

10. Reflex Angle
A reflex angle is an angle greater than 180 degrees (but less than 360)
