TRIGONOMETRY relationships in triangles!

WHY?-http://tinypic.the angle wont matter, because even if its in a different quadrant, the squaring of the sin(theta) and cos(theta) in the Pythagorean theorem eliminates all -ves. Still 52 is in that quadrant.......
angle A = 52 degrees

the sum of the square of Sin A and Cos A is lways 1, why?

THIS IS WRITTEN AS:

(Sin A) ^2 + (Cos A) ^2 = 1

WHY?
