##### Proof by Shear Transformation
This app allows you to explore geometric proof that is a variation of the original Euclid’s proof. In this proof, the shear transformation is used to change the shapes without changing their areas.

##### Reflection Clock
Press the Reflect button to reflect the triangle in the minute hand. Press again to reflect the result in the second hand. Can you describe the motion of the second reflected image?

##### Combination of Reflections through Parallel Lines
Press Reﬂect twice. Now drag point I so the orange triangle lies over the image under the second reﬂection.  Can you describe another transformation equivalent to the two reflections?

##### Combination of Reﬂections through Oblique Lines
Set the rotation angle and drag the center of rotation O so that the orange triangle sits on top of the image under the second reﬂection.  Can you describe another transformation equivalent to the two reflections?
