i love eliminating options based on logic 
option B is rubbish because they cannot be equal to each other and we don't have coordinates to use distence formula to see if they equal or not so it just make no sense

will.h · Answer

Option C is also rubbish because they are quite the opposite there are common side which is CP so...

will.h · Answer

sorry for the 1st comment of mine i meant option A to be eliminated

will.h · Answer

So it has to be B or D 
thoughts?

chpatterson · Answer

HINT: line CP is the perpendicular bisector of segment AB

will.h · Answer

which divide it to equal sides 
so i take it as the triangles are congruent by the SAS

yet i cannot determine A or D because if it was A then D is also right

will.h · Answer

i mean B not A

will.h · Answer

if B is right then D is also right!

will.h · Answer

Gotta go 
consult another guy am not quite certain
