Finding Midpoints & Endpoints

Front

What is the formula to find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

Given the midpoint M and one endpoint A, how can you find the other endpoint B?

Back

B = (2M - A)

Front

If the endpoints of a line segment are (2, 3) and (4, 7), what is the midpoint?

Back

Midpoint = (3, 5)
