lol, but i'm proud of myself. i mean i figured this out all by myself :D It's the Thales' Theorem. "	 The Thales’ Theorem states that in geometry, if A, B and C are points on a circle where the line AC is a diameter of the circle, then the angle ABC is a right angle. This is always true because the line segments, AX, (let X be the center of the circle), BX, and CX, are all equal. They are equal because they are all radiuses of the circle. Then XBC and XBA form isosceles triangles. Since the base angles of isosceles triangles are equal then angles XBC and XCB are equal and angles BAX and ABX are equal. Let H equal angle BAX and J equal angle XBC. The 3 internal angles of the ABC triangle are H, H + J and J. Since the sum of the angles of a triangle is 180 we get the equation of H+(H+J)+J=180. Then we get 2H+2J=180, and from there we simplify to H+J=90. That means the last remaining angle must be 90 degrees, since there are only 180 degrees in a triangle and 2 of them equal 90, 180-90=90." and I"m being recommended for Honors Trigonometry next year -_- i'm scared. xD
