More on Tessellations

In this tessellations worksheet, 10th graders solve 3 different word problems that include creating various tessellations. First, they group pentagons around a vertex so the angles add up to 360 and determine whether the pentagons can tessellate in the plane. Then, students write a convincing argument that, given any trapezoid, they can always form a parallelogram using 2 congruent copies of the trapezoid.
