WebThe angle bisector of an angle of a triangle is a straight line that divides the angle into two congruent angles. The three angle bisectors of the angles of a triangle meet in a single point, called the incenter . Here, I is the incenter of Δ P Q R . The incenter is equidistant from the sides of the triangle. That is, P I = Q I = R I . Webactually name of side bisector is median it equally divides side into two parts. Also No, unless you have equilateral or isosceles triangle. bisector from not equal angles. so if isosceles triangle has angles: 30, 30 and 120. bisector will be median and also a perpendicular if you construct it from 120 degree angle.
