question is: find the coordinates of midpoint P of line BC. Calculate lengths of AP, BP, CP. P is ? (midpoint of BC which bisects <A(0,0), B(0, 2k), C(2h,0). Thank you.

Answer 1

the midpoint is the average of the endpoints.

So, for BC, P=(h,k)

Now just use your distance formula to get the required lengths.
