question 12

Explanation:

Reflection is a transformation that flips a figure over a line of reflection. When a triangle is flipped over the x - axis, it is being reflected over the x - axis. Rotation turns a figure around a point, translation slides a figure, and dilation changes the size of a figure.

Reflection
