We reviewed the concept of slope today and how it relates to parallel and perpendicular lines. Parallel lines have equal slopes while perpendicular lines have slopes that are negative reciprocals. Using these two concepts to confirm various properties about geometric shapes is what the 3 examples were about that we went over in the notes. Graphing points to determine the figure and then confirming perpendicular or parallel lines on the figure are the skills we worked on today.
