The shape is an equilateral triangle.
a)Does the shape have rotational symmetry? If so,identify the angle of rotation.
b)Does the shape tessellate?

I don't know what to do for the first part.But I think part B is yes because it has no overlaps or gaps. Please help

    if you rotate it 60 degrees (360/3), it looks exactly like it did before since there is a corner at every 60 degrees

    your answer to the second part is correct. Unlike circles, you can cover your flat roof with them with no leaks.
