Construction and Properties of Perpendicular Lines
2017-09-13 17:13
This applet demonstrates the geometric construction and properties of perpendicular lines. Using GeoGebra's line, slope, and angle tools, it visually illustrates how to construct a perpendicular line and verifies the slope relationship (negative reciprocals) and the 90-degree intersection angle between two perpendicular lines. Ideal for teaching plane and coordinate geometry.
