Find the coordinates of midpoint P of segment BC. Then Calculate the lengths of segments AP, BP, and CP.
Is point P the circumcenter of triangle ABC?
Is point A on the perpendicular bisector of segment BC? (Always, never or sometimes)
Thank you for your help.

The coordinates of point B are (0, 2k) and that of point C are (2h, 0). The mid point of BC lies at P and its coordinates are `((0+2h)/2, (2k+0)/2)` = (h, k)
The length of AP is `sqrt(h^2 + k^2)` , the length of BP is `sqrt(h^2 + k^2)` , the length of CP is `sqrt(h^2 + k^2)`
The point P is the circum-center of triangle ABC.
Looking at the length of AP, PC and AC,
`AP^2 = h^2 + k^2` , `PC^2 = h^2 + k^2` and `AC = 4h^2`
Point A is on the perpendicular bisector of segment BC only when h = k.
