Question

With a two dimensional surface, if we take (2, 1) as the center point and consider a transformation with a rotation angle of 45°, then point (3.3) is transformed into point [1-3]​

Answer 1

Answer:

The rotation angle of 45 can be either clockwise or counterclockwise. The distance from (2,1) to the point of transformation must be the same as the distance from (2,1) to (3,3) which is easily found to be 5^½
