yeah, what does it mean to map itself??
ganeshie8 (ganeshie8):
how many degrees you need to rotate so that the triangle looks looks exactly like it was originally ?
ganeshie8 (ganeshie8):
I think you need to rotate the triangle by `360/3 = 120` degrees for it to map exactly over itself. it doesn't matter which direction you rotate
