  2. What kind of a geometrical shape forms this design?

  3. INDICATORS: • Creating tessellations using equilateral triangle, regular hexagon, rhombus, and trapezoid. • Explaining whether tessellation can be created using a square and an equilateral triangle, and justifying the answer with a drawing. • Determining the sum of measures of the angles where the vertices of the figures meet in the tessellations. • Determining the name of two figures that cannot be used to create a tessellation and justifying the answer with a drawing. • Creating tessellation using other pattern blocks.

  4. Tessellations A pattern formmed by repeating figures that fit together without gaps or overlaps is a tessellation. Tessellations are formed using translation(slides), reflection(flips), or rotation(turns) of congruent figures

  5. Three Common Transformations 1. Translation, which is a slide of one side of the polygon. 2. Reflection, which is a flip or mirror image of one side of the polygon. 3. Rotation, which is a turn of a side around one vertex of the polygon.
