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.
RightAngle.png
SquareRightAngles.png
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.
ObtuseAngle.png
This angle is bigger than a right angle so it is obtuse.
An angle that is smaller than a right angle is called acute.
AcuteAngle.png
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 (°).
There are 360 degrees (360°) in a full circle.
AngleAroundaPoint.png
The total angle around a point is 360°.
There are 90 degrees (90°) in a right angle.
SquareRightAngles.png
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.
135degrees.png
This angle is bigger than 90° so it is obtuse.
An angle that is smaller than 90° is called acute.
45degrees.png
This angle is smaller than a 90° so it is acute.
