How do you find the midpoint of a line segment?

Back

To find the midpoint of a line segment, average the x-coordinates and the y-coordinates of the endpoints. If the endpoints are (x1, y1) and (x2, y2), the midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.
