Geometry Question #3
Posted:

Geometry Question #3: We had students identify the transformation as a dilation (of 1). I called the State to see if they would allow credit if a student chose choice #2 dilation. Their response: "No because there are too many assumptions that must be made." And they wanted proof that a rotation of 180 degrees is the same as a dilation of 1. Apparently this is not common knowledge in the math world. Very frustrating.....very frustrating.....
