Congruency and Similar triangles test tomorrow, most of it seems all right, but stuff like THIS is really confusing! Help plz.

ABCD and ARQP are squares, right? (This isnt stated but from the diagram (if drawn to scale) they look like squares so I presume this is the case.)
Then I can see that rotating ΔBAR through 90° clockwise will fit it into ΔDAP. Hence the two triangles are congruent (and DÂP = BÂR).
PS: Actually, if you want a more analytical proof, thats quite straightforward too
DÂP + PÂB = 90°
BÂR + PÂB = 90°
∴ DÂP = BÂR

Yeah sorry I forgot to mention that. They are both squares
