A half-turn is a 180 degree rotation. Apply the half turn centered at (3,2) to the point (7,1).

Question

Find coordinates of the image point. Find coordinates for the image of (x,y).

Answer 1

Moxa, a 180 degree turn would have the point opposite (7,1) from (3,2) and the same distance. It would be -4 on the x-axis and 1 on the y-axis, so our new point would be (3-4,2+1) = (-1,3).

 

Hope this helps!
