Slope Of Parallel Lines Worksheet. Given Slopes of Two Lines Determine if the Lines are Parallel, Perpendicular, or Neither These Parallel and Perpendicular Lines Worksheets. Found worksheet you are looking for?
I explain why at the end. Prove that two parallel lines have equal slopes. Well, you wouldn't be walking up or down on a hill like this.
That means… They have equal slopes, therefore the lines are parallel to each other!
Apply slope formula, find whether the lines are parallel or perpendicular.
You will identify all of the angles formed by this intersection as corresponding angles, vertical angles, alternate interior. All this means is that if two lines are perpendicular, then they will have opposite signs and one is the "flip" of the other. Slope is the measure of the "steepness" of a line.
