Transformations In the Plane

A program for the TI-83 for visualizing transformational geometry and linear algebra concepts
By Jim Olsen

The transformation matrix is in matrix [A] (edit it using MATRIX-EDIT).  This program transforms (rotates, reflects, dilates, deforms) a triangle (or other figure).  The figure is stored in matrix [B].  The columns of matrix [B] are the vertices of the figure.  Matrix [B] must have 2 rows.  It can have any number of columns.  If the dimensions of [B] are 2x3, then a triangle will be transformed. (Edit [B] using MATRIX-EDIT.  Scalene right triangles are recommended).

When executing the (TRANSFM) program:
the transformation matrix is shown (press ENTER);
the original figure is shown (press ENTER);
the transformed figure is shown.
