Perpendicular Lines- two lines that intersect and the point of intersection form a right angle.
1. Would there be a consequence if the lines were not perpendicular?
The lines would not form the correct angle, therefore causing the panels to form different shapes other than rectangles.
2. How do you determine the slope of perpendicular lines?
You take two points from each line and enter them in the equation (y2-y1/x2-x1).
