Geometry:
Let's review how to find the length & midpoint of a line segment. Is the length always positive? Can a line or ray have a midpoint? Also, let's determine whether two lines are parallel or perpendicular (or neither); and write equations of parallel & perpendicular lines. Why do you think vertical & horizontal lines are perpendicular? Why are the lines y = 2 and y = -4 parallel?
