Question

drawrotational symmetry of square​

Answer 1

Answer:

A half-turn means rotation by 180° a quarter-turn means rotation by 90°. ... In a complete turn (of 360°), the number of times an object looks exactly the same is called the order of rotational symmetry. The order of symmetry of a square, for example, is 4 while, for an equilateral triangle, it is 3.
