1. when rotating a shape around a non - origin point, what must you do after performing the rotation?

a. change the sign of the new y - coordinate
b. reflect the figure over the x - axis
c. swap the coordinates
d. translate the figure back to its original position

Explanation:

When rotating a shape around a non - origin point, first we perform the rotation as if the point was the origin. But since the original position of the shape is related to the non - origin point, after rotation, we need to move the shape back to its original relative position. This is achieved by translation. Changing the sign of the new y - coordinate, reflecting over the x - axis, or swapping coordinates are not the correct follow - up steps for a non - origin point rotation.

Answer:

D. Translate the figure back to its original position
