Creating Parallel and Perpendicular Lines
Your task
Using the geogebra graphing calculator, graph line segments AC and BD
A(-2, 5) C(3, 8)
B(-3, 7) D(?,?)
Find the coordinates for D, so that your line segments are parallel.
Graph points
How do you know your line segments are parallel?
Using the same coordinates for points A, C and B, find the coordinates for D so that your line segments are perpendicular.
How do you know your line segments are perpendicular?
