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.
