Ex 14.3 | Question 3

Text Solution

What is unknown?

The figures have rotational symmetry of order more than \(1\).

Reasoning:

Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appears the same. The order of symmetry is the number of positions the object looks the same in a \(360^\circ\) rotation.

Steps:

Yes, because every line through the centre forms a line of symmetry and it has rotational symmetry around the centre for every angle.
