XY is the bisector of LVXU. By the Angle Bisector Theorem, 2m + 9 5m —6 3m Substitute the value of m to find VY. 2m — 9 2(5) - 9 Find the measure. Two rays that meet at a point and extend indefinitely form an angle. The two rays are the sides of the angle. The point at which they meet is the vertex of the angle. An angle separates the plane into the interior region, the exterior region, and the angle itself. Angles are measured in degrees using a protractor. .
