what is the median of a triangle?,  | It is a segment whose endpoints are at the vertex and the midpoint of the opposite side. |
What is the altitude of a triangle?,  | It is a perpendicular segment from the vertex to the line containing the opposite side. |
Theorem 4.5:Perpendicular Bisector Theorem. If point C lies on the perpendicualr bisector of segment CD, the point C is...,  | equidistant from the endpoints of the segment (Points A and B). |
Theorem 4.6: Converse of the perpendicular bisector theorem. If a point (point C) is equidistant from the endpoints of the segment (AB), then it is on the....,  | perpendicular bisector of a segment |
Theorem 4.7:Angle Bisector Theorem. If a point (point D) lies on the bisector of an angle, then the point is .....,  | equidistant from the sides of the angle. |
Theorem 4.8: Converse of the Angle Bisector Theorem. If a point (point D) lies equidistant from the sides of an angle (sides AC and AB), then the point lies....,  | on the perpendicular bisector of an angle. |
