Show that \BOC = \BAC 2 + 900. WebYes; If two vertices (of a triangle inscribed within a circle) are opposite each other, they lie on the diameter. By the inscribed angle theorem, the angle opposite the arc determined by the diameter (whose measure is 180) has a measure of 90, making it a right triangle. Good job!
