Analytical Geometry: Quadrilaterals and Triangles using Length and Slope Students pick a card that has a series of co-ordinates on one side and the shape these co-ordinates creates on the other. They they use the blank worksheets to graph the points. The worksheets act as graphic organizers so that students can structure the process in determining what shape it is using the length of the segments between the points and the slopes. Full solutions are provided for all the shape types. Shapes are

Finding the area of a triangle using three points can be difficult for students because of the number of steps. This activity is designed to get students out of their seats a little and guide them to the solution. If they get stuck they can check the hints and be on their way to the answer.
