In this lesson we are going to talk about some special segments within triangles. The first one (there are a few) is the perpendicular bisector. A perpendicular bisector is a line or line segment that passes through the midpoint and is perpendicular to that side. There are a couple of theorems regarding the perpendicular bisector. One of them says that any point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment. You'll also learn about the median, the altitude, and the angle bisector. There are a couple of theorems regarding the angle bisector, which you'll learn in this lesson.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
