Once the Mira is removed the student as all of the components of the transformation left behind on paper. This is done by looking through the Mira and tracing the image in a surprisingly intuitive way.

Then once students understand how to use the Mira they are then able to go further by tracing their reflections. The Mira forces students to map one image over another to varied degrees but nevertheless, this mapping and moving of the Mira opens doors to conceptual understanding of reflections. When using a mirror students lose sight of the complete original at whatever point they place the mirror. The Mira has the advantage over the mirror in that it allows students to continue to see their original image at all times. Miras help students in geometry with the concept of symmetry and reflections as a transformation in 2 two dimensional geometry.
This is the basic purpose and use of the Mira, the true depth of conceptual ability the Mira provides is in how it is applied to a task. The result is being able to map one image over another. The bevel compensates for that bend as it meets the work surface during use. The Mira works much like a mirror but with the simultaneous advantage of being able to see through. The reason for this is because the Mira bends light. Regardless of which edge the Mira has been laid on to view the pane the bevelled edge must face the user. The Mira has a bevel on each long side of a single face of the large pane. The short length of the “T” is used for stability as the Miras are always laid on their side with the “T” shape both on the paper and pointing straight up. The Mira is then to the user’s perspective a large red pane which is transparent and tinted red. Miras are red plastic forms in the shape of a “T” or "I" and approximately 4 to 5 inches deep.
