# Shape and symmetry: To investigate angles within shapes

In this lesson, you will recap on the names of different types of angles. We will be looking specifically at angles within different shapes. You will be drawing and investigating different shapes containing a variety of angles. Pupils investigate a series of statements about the angles within shapes, justifying whether they are always, sometimes or never true.
