Geometry proof perpendicular lines
WebNov 28, 2024 · Figure 1.4. 1. A midpoint is a point on a line segment that divides it into two congruent segments. Figure 1.4. 2. Because A B = B C, B is the midpoint of A C ¯. Any line segment will have exactly one midpoint. When points are plotted in the coordinate plane, we can use a formula to find the midpoint between them.
