If a point is translated by <-1, 1> and then rotated 270 degrees, what is the new position of the point (1, 2)?

Back

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

What happens to the coordinates of a point (x, y) when it is reflected over the x-axis?

Back

The coordinates become (x, -y).
