A diagram showing two lines crossing to make an angle.

An angle is the space between two straight lines that cross each other.

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.

A diagram showing two lines crossing to form an angle.

An angle is the space between two straight lines that cross each other.

Angles are measured in degrees (°).

There are 360 degrees (360°) in a full circle.

There are 90 degrees (90°) in a right angle.

An angle that is bigger than 90° is called obtuse.

An angle that is smaller than 90° is called acute.
