Distance, Midpoint & Fractional Distance

Front

What is the formula to find the midpoint between two points (x1, y1) and (x2, y2)?

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Front

If point M is the midpoint of segment AB, and A has coordinates (x1, y1), how can we find the coordinates of point B if we know M?

Back

If M = (xm, ym), then B = (2*xm - x1, 2*ym - y1).

Front

What is the significance of the midpoint in geometry?

Back

The midpoint divides a line segment into two equal parts.

Front

How do you find the endpoint of a segment if you know one endpoint and the midpoint?

Back

If A is the known endpoint and M is the midpoint, then B = (2*xm - x1, 2*ym - y1).
