#### Module Description

This module was developed using Geometer's SketchPad (GSP), and provides graphical representation of matrices in R^{2}.

This module is designed to show matrices and the resultant matrices (of matrix operations) from a geometric perspective.

Matrices are formed by dragging the points *P*, *Q* and *R*, *S* respectively.
The resulting matrices from multiplying two matrices are displayed in gray and brown colors.

The "Reset" button changes both matrices to the identity matrix.
