Question

confusing geometry help?

Answer 1

you should be able to take the end point you know and minus the midpoint from it. which will give you the length of the segment from the midpoint to endpoint. since that's exactly half the line, you can then take the midpoint and minus the length you got from it to find the other end point.

Answer 2

I just needed to draw it out. Thanks for the help!

Answer 3

no problem.
