A parallelogram is a 4-sided figure. In a parallelogram, opposite sides and opposite angles are equal sizes (congruent), and opposite sides are parallel.

A translation tessellation, also called a slide translation, gets its symmetry by simply sssssliding the outline of one edge along to a new position on the opposite side of the tile, without turning the edge or flipping it over.

This project works with any rhomboid. In it, you can make a tessellation that has translational (slide) symmetry. In the Heesch way of describing tessellations, the kind of tessellation we'll make in this project is called TTTT because in the tile outlines, the top and bottom edges look the same, and the left and right sides also look the same as one another.

Teachers: It's probably best to go through one with the entire class watching, then give each student a print-out of the lesson & let them work alone-- with you wandering around giving person-to-person assistance & encouragement.
