Take a semi-circle, call the diameter AB. and use as the hypotenuese of a triangle. Mark any point on the circumference as C and form a triangle by joining A to C and B to C. What is the angle formed at C?
I think it's always a right angle (especially if the length of AC = BC).
But how do i prove it?
