A diagram showing a right angle between two lines. | There are 4 right angles in a square or a rectangle. |
- An angle that is bigger than a right angle is called obtuse.

Upper Key Stage 2
Meaning
An angle is the space between two straight lines that cross each other.
About Angles
The total angle around a point is 360°. |
- There are 90 degrees (90°) in a right angle.
A diagram showing that a right angle is 90°. | There are 4 right angles in a square or a rectangle so the total angles inside added together makes 360° |
This angle is bigger than 90° so it is obtuse. |
This angle is smaller than a 90° so it is acute. |
