6th Maths : Term 3 Unit 4 : Symmetry : Summary

**Summary**

● The line that divides any figure into two equal
halves such that each half exactly coincides with the other is known as the **line
of symmetry** or **axis of symmetry.**

● A shape has **reflection symmetry** if it has
a **line of symmetry**.

● An object is said to have a **rotational symmetry**
if it looks the same after being rotated about its centre through an angle less
than 360°.

● The total number of times a figure coincides with
itself in one complete rotation is called the **order of rotational symmetry.**

**● Translation symmetry** occurs when an object slides to a new position.
The sliding movement involves neither rotation nor reflection.
