GEOMETRY Lesson 4.1: PROPERTIES OF TRIANGLES – PERPENDICULAR BISECTORS AND ANGLE BISECTORS IN TRIANGLES NOTES Objective: To identify and use perpendicular bisectors and angle bisectors in triangles PERPENDICULAR BISECTOR A perpendicular bisector of a side of a triangle is a line, segment, or ray that passes through the midpoint of the side and is perpendicular to that side. Since a triangle has three sides, there are three perpendicular bisectors in a triangle. The perpendicular bisectors of a triangle intersect at a common point. When three or more lines intersect at a common point, the lines are called concurrent lines, and their point of intersection is called the point of concurrency. The point of concurrency of the perpendicular bisectors of a triangle is called the circumcenter.
