Given quadrilateral RSTU, follow the steps to tell which sides (if any) are parallel and which are perpendicular for the coordinates of the vertices. R(-1, 1), S(1, -2), T(5, 0), U(3, 3) Part 1 Graph the coordinates of quadrilateral RSTU on a coordinate plane. Assign the appropriate variables to the coordinates. Part 2 Find the slope of each side of the RSTU, using the two points that creates the side. Slope of side RS= Slope of side ST= Slope of side TU= Slope of side UR= Part 3 Use the slope of each side to name the pairs of parallel and perpendicular sides. For each relationship between a pair of sides, explain in complete sentences, why the relationship between the sides exists.
