The statement that tessellations using more than one type of regular polygon are called semi-regular tessellations is:
A. True
Explanation:
1. A tessellation is a pattern of shapes that fit perfectly together without any gaps or overlaps.
2. Regular polygons have equal sides and angles, such as squares and equilateral triangles.
3. Semi-regular tessellations are formed by using more than one type of regular polygon, but the arrangement must follow a specific pattern.
4. An example of a semi-regular tessellation is the combination of squares and equilateral triangles in a specific repeating pattern.
In conclusion, the statement is true because semi-regular tessellations do indeed incorporate more than one type of regular polygon in a structured manner to create the tessellation.
