Question

What is the single transformation maps figure abcd onto figure a’b’c’d’

Answer 1

Looking at the figures, we can see that the quadrilaterals are not in the same orientation.

That means we need a rotation to transform ABCD into A'B'C'D'.

Then, we can also see that the points C and C' are the same, that means this point is the center of rotation.

Therefore the answer is a rotation about point C.
