Key Stage 2
Meaning
A right angle is shown in the following diagram.
 |
| A diagram showing a right angle between two lines. |
Key Stage 3
Meaning
A right angle is an angle of exactly 90° between two lines.
About Right Angles
- right angles are labelled between two lines that cross over at 90° to each other.
- Two lines at right angles may be called perpendicular.
- A line at right angles to a surface is called a normal line.
- The angles inside a square or rectangle are right angles.
