Tesselations

• What a tessellation is
• Any triangle can be used to tessellate.
• Certain regular polygons can be used to tessellate: equilateral triangles, squares, hexagons. The others will not work.

Transformations:
what they do and that they preserve congruence

• translations: A vector gives the direction and distance.
• rotations: needs a center and an angle
• reflections: needs a mirror line
• lines of symmetry
