Lower Key Stage 2
Meaning
An angle is the space between two straight lines that cross each other.
About Angles
- Angles are labelled between two lines that cross over.
- The angles inside a square or rectangle are described as right angles.
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.
This angle is bigger than a right angle so it is obtuse. |
- An angle that is smaller than a right angle is called acute.
This angle is smaller than a right angle so it is acute. |
Upper Key Stage 2
Meaning
An angle is the space between two straight lines that cross each other.
About Angles
- Angles are measured in degrees (°).
- A protractor can be used to measure the angle between to lines.
- There are 360 degrees (360°) around a point.
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. |
- The angle on a straight line is 180°.
A diagram showing 180° on a line. | These two angles add up to 180° because they are part of a straight line. |
- A reflex angle is the angle on the opposite side of another angle.
An angle added to its reflex angle makes 360°. |
Key Stage 3
Meaning
An angle is the space between two intersecting straight lines.
About Angles
- Angles are measured in degrees (°).
- A protractor can be used to measure the angle between two intersecting lines.
- There are 360 degrees (360°) around a point.
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. |
- The angle on a straight line is 180°.
A diagram showing 180° on a line. | These two angles add up to 180° because they are part of a straight line. |
- A reflex angle is the angle on the opposite side of another angle.
An angle added to its reflex angle makes 360°. |
Key Stage 4
Meaning
An angle is the space between two intersecting straight lines.
About Angles
- Angles are measured in degrees (°).
- A protractor can be used to measure the angle between two intersecting lines.
- There are 360 degrees (360°) around a point.
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. |
- The angle on a straight line is 180°.
A diagram showing 180° on a line. | These two angles add up to 180° because they are part of a straight line. |
- A reflex angle is the angle on the opposite side of another angle.
An angle added to its reflex angle makes 360°. |
