Objective: Find a method to tessellates the plane with any triangle. Introduce regular and semi-regular tessellations.
Tessellations by Triangles and Quadrilaterals
- Convince yourself that the parallelogram below will tessellate the plane. Draw your tessellation on a separate piece of paper. It should cover 1/4 of your page.
- Show that a square tessellates the plane and show that a rectangle tessellates the plane. Your tessellations should cover 1/4 of your page.
- Draw an acute, an obtuse and a right triangle. Now convince yourself of the fact that two congruent copies of the same triangle fit together to form a parallelogram or a rectangle.
- Why does this imply that all triangles will tessellate the plane?
Tessellations of the Plane by Regular Polygons
A regular tessellation is a tessellation made of regular, congruent, convex polygons.
A semi-regular tessellation is a tessellation made of regular polygons of two or more types so that the arrangement of polygons at each vertex is the same.
- What is the common name for a regular 3-gon?
- What is the common name for a regular 4-gon?
