Parallel Lines have the same slope Perpendicular Lines have slopes that are negative reciprocals of each other.
not parallel (different slopes). Next, show that the legs of the trapezoid are congruent. Example 2: Prove that quadrilateral MILK with the vertices M(1,3), I(-1,1), L(-1, -2), and K(4,3) is an isosceles trapezoid. Show: Formula: 2 Work Step 1: Calculate the Slopes of all four sides to show Step 2: Calculate the distance of
