Realize that the diameter of the circle is the hypotenuse of the triangle.
Any inscribed angle in a circle measures one-half the intercepted arc.
But that is the “other” semicircle which measures .
I need to write a proof and prove that: any triangle inscribed in a semicircle is a right triangle.
I realize that it is right, but I am unsure how to prove that it is true.
Can anyone help me with an idea of where to start?
