Question

The shape below is an equilateral triangle. a) Does the shape have rotational symmetry? If so, identify the angle of rotation. b) Does the shape tessellate?The image shows an equilateral triangle." i really need help to find this out

Answer 1

Below.

Explanation:

a) An equilibrium does have rotational symmetry.

The angle of rotation is 120 degrees .

It has Rotational symmetry of order 3.

b) It does tessellate because the angle in the triangle divides exactly into 360 : 360 / 60 = 6.
