Lower Key Stage 2

Meaning

 
A diagram showing two lines crossing to make an angle.

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

 
A diagram showing two lines crossing to form an angle.

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°
An angle that is bigger than 90° is called obtuse.
 
 This angle is bigger than 90° so it is obtuse.
An angle that is smaller than 90° is called acute.
 
 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

 
A diagram showing two intersecting crossing to form an angle.

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°
An angle that is bigger than 90° is called obtuse.
 
 This angle is bigger than 90° so it is obtuse.
An angle that is smaller than 90° is called acute.
 
 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

 
A diagram showing two intersecting crossing to form an angle.

An angle is the space between two intersecting straight lines.

 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°
An angle that is bigger than 90° is called obtuse.
 
 This angle is bigger than 90° so it is obtuse.
An angle that is smaller than 90° is called acute.
 
 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°.
