Worksheet demonstrating how to use coordinate geometry to identify a rhombus by analyzing diagonal slopes and midpoints.
A worksheet titled "Using Coordinate Geometry to Determine the Type of Quadrilateral" showing a graph with points L(3,3), M(1,2), N(3,1), and O(5,2) forming a quadrilateral. Handwritten calculations for slope and midpoint of diagonals are shown, concluding that LMNO is a rhombus because its diagonals are perpendicular and bisect each other.
