Nadya, you need to complete your question, whether the trig identity holds only for a right angled triangle. If not, can this forum gives other example the proof of (sinx)^2+(cosx)^2=1 without using pythagoras formula for the triangle?Thx.

Whether the trig identity (sinx)^2+(cosx)^2=1 only can be created using a triangle?
