HI,sorry to say that but there is nothing to understand here. It is a rule that an inscribed angle is equal to 1/2 the measure of the adjacent arc. But if the angle is a central one, it is equal to the arc in measure. If you can not remember it think simply of a triangle. It has sum of angles 180 degrees and when inscribed this sum is measured by 360 degrees of the circle. Hope this can help
