Maths this week

This week we have been learning about angles and degrees.
An angle is where something meets another thing that goes in a different direction eg:  This is a 90 degree angle called a right angle here are all the different types of angles.

Here is the tool to measure angles.

It also shows how it works.
There are obtuse angles,right angles and acute angles. eg

Obtuse are more then 90 degrees right are exactly 90 degrees and acute are less then 90.
