Compare and contrast angle bisectors and segment bisectors

1) A segment bisector is one which divides a line segment into two equal parts. And, the angle it forms is 90° with the two equal parts. Example, an isosceles triangle has three segment bisector which divided the side of the triangle into equal parts. 

2) Angle bisectors divide an angle into two angles, Example, an angle in an equilateral triangle is 60°. Thus, the angle bisector will divide the 60° angle into two equal angles i.e. 30°
