Coordinate Geometry of Quadrilaterals

1.  

   Review how to determine whether or not lines and line segments in the coordinate plane are parallel or perpendicular by computing and comparing the slopes.

2.  

   Present how to use slope, midpoint and distance formula to determine from the coordinates of the vertices whether a quadrilateral is a parallelogram, rectangle, square, rhombus, trapezoid, or isosceles trapezoid.

3.  

   Provide examples that allow practice using coordinate geometry to classify quadrilaterals in a coordinate plane.

This packet should help a learner seeking to understand how to determine from the coordinates of the vertices whether a quadrilateral is a parallelogram, rectangle, square, rhombus, trapezoid, or isosceles trapezoid.
