Endpoint (x,y) of a Segment Given Midpoint & Other Endpoint

Directions: 1) In the applet below, note the segment with endpoint B and MIDPOINT M. 2) Algebraically determine the coordinates of the other endpoint (x, y). 3) Enter in these coordinates in the input boxes provided in the upper left hand corner. 4) If you get the problem correct, the applet will indicate this to you. If not, keep trying. 5) Click the "New Problem" button to create a new segment with different endpoints. 6) Repeat steps (1) - (5). 7) Repeat steps (5) - (7) as many times as you need in order to master this concept!
