# To identify lines of symmetry in 2-D shapes

In this lesson, you will be revising the names of different types of 2D shapes. We will begin to explore what symmetry is and how to recognise lines of symmetry in 2-D shapes. We will develop strong mathematical language about shape and we will investigate lines of symmetry in a variety of quadrilaterals and triangles.
