Stained glass is a very popular design selection for
church and cathedral windows. Determine whether
the pattern is a tessellation. If so, describe it as
uniform, regular, semi-regular, or not uniform.

A. not a tessellation
B. regular tessellation
The pattern is a tessellation C. semi-regular tessellation
because at the different vertices D. non-uniform tessellation
the sum of the angles is 360°.
Answer The tessellation is not uniform Answer
because each vertex does not
have the same arrangement of
shapes and angles.
