    for part a), how many lines can you draw such that you mirror the figure over that line to have it match up with itself?

    now onto part b) is it possible to rotate this figure such that it lines up with the original image? the angle must be between 0 and 360 degrees (not including 360 degrees)

    how much do you have to rotate it to make it line up with the original?

    180 degree rotation

    so because this is possible, this figure does have rotational symmetry

    So the answer for 4b would be Yes, 180 degree rotation
