Can't understand how to write the problem in normal format

hello ! I'm having this geometry problem: H is the orthocenter of triangle ABC. The points D and E on the AC side are as follows,
that AD = DH, CE = EH. The lines BP and UR intersect the sides BC and AB at points P and Q
, respectively. The circumscribed circles of triangles BP and BP intersect the sides AB and
In C, at points X and y, respectively. Prove that the centers of the circumscribed circles of the triangles are
QHA and PHP lie on a straight XY.
And i have some troubles, for example how can denote the othocenter or write, that triangles are
QHA and PHP lie on a straight XY.
Help me please :( i even ready to pay money (if u'll send the alphageomtry's solution)
