how do you use the distance formula and the slope to classify a quadrilateral

Question

precal · Answer

Welcome to openstudy.  The distance formula gives you the distance between 2 points.  In geometry, we are always concern with the length of the sides of the quadrilaterals.  Ie if all sides are equal then the quadrilateral is a square.  We use the slope formula to tell you if the sides are going up or down and I am pretty sure to find perpendicular lines. so if the slope is 3 and -1/3 then we know that those two lines are at a 90 degree angle and we care a lot about that in geometry.
