Students love discovery exercises. With Geogebra, the user can move and change objects with the click of a mouse. In this exercise, when you move any point, a new triangle is formed. This allows the student to create any triangular shape of their choosing. Geogebra, then, automatically updates and displays all the new measurements.Through a step by step discovery process worksheet, students uncover the Cosine Law. This allows them to clearly see its derivation and thus better understand its application. The lines in the Geogebra triangle are color coded to help students identify each of the three sides and their corresponding angles. A necessity to understand and apply the Cosine Law.

Geogebra, a free program, is quickly and easily downloaded from the internet to both computers and tablets (as an app). Students can work individually in a computer lab or you can use a single computer and projector and work through the exercise as a group. Alternatively, you could use the flipped classroom model and have them complete the exercise at home allowing class time to further develop the ideas presented.

Four pdf pages of guided exercises, questions and calculations along with two geogebra files will provide your students with a complete resource to independently explore this topic.
