# Angles around a point

A full turn is 360 degrees, so the angles around a point always add up to 360 degrees. Can you look at these diagrams and work out what the missing angles are, WITHOUT using a protractor?

## What are angles in KS2 maths?

In KS2 (Key Stage 2) maths, angles are an important concept that your child will learn about.

An angle is a measure of the space between two lines that meet at a point, which is called the vertex. You can think of it like the corner of a room or the point where two roads cross. The size of an angle tells us how wide or narrow this space is.

## What types of angles should KS2 children learn about?

• Right angles
These angles measure exactly 90 degrees and look like the corner of a square or a book.
• Acute angles
This is an angle that is less than 90 degrees. It’s smaller and looks more pointy.
• Obtuse angles
This type if angle is more than 90 degrees but less than 180 degrees. It looks wider or more open.
• Straight angles
This angle is exactly 180 degrees, forming a straight line.

Your KS2 child will be taught that angles are measured in degrees (°). And a full circle is 360 degrees, so if you go all the way around a point, you’ve turned 360 degrees.
