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 (°).
A protractor can be used to measure the angle between to lines.
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.
RightAngleDegree.png
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.
The angle on a straight line is 180°.
AngleonaLine.png
TwoAnglesonaLine.png
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.
ReflexAngle.png
 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°) in a full circle.
AngleAroundaPoint.png
 The total angle around a point is 360°.
There are 90 degrees (90°) in a right angle.
RightAngleDegree.png
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.
The angle on a straight line is 180°.
AngleonaLine.png
TwoAnglesonaLine.png
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.
