Angle ABC is 90 degrees (whenever you connect a diameter AC to a point B on the circumference of a circle, the angle at B is 90). The hypotenuse of ABC is 2 (it's double the radius), and one side is 1, which means the remaining side is root(3), by Pythagoras, or by noticing we must have a 30-60-90 triangle. Base*height/2 = root(3)/2.
