Triangular Tessellation
Tessellation is the process of creating a two-dimensional plane using the repetition of a geometric shape with no overlaps and no gaps. Triangular tessellation specifically involves creating a tessellated pattern using triangles.
Types of Triangular Tessellation
There are several types of triangular tessellation patterns:
- Regular Triangular Tessellation: In this pattern, equilateral triangles are used to create the tessellated design. All the angles and side lengths of the triangles are equal.
- Semi-Regular Triangular Tessellation: This pattern involves using different types of triangles (e.g., right-angled, isosceles) to create the tessellation.
- Irregular Triangular Tessellation: In this type, a combination of triangles with varying angles and side lengths is used to create the tessellated design.
Properties of Triangular Tessellation
When creating a triangular tessellation, it's important to consider the following properties:
- Vertex Angle: The angle formed at the vertex of each triangle in the tessellation.
- Edge Length: The length of each side of the triangles in the tessellated pattern.
- Interior Angle: The angle formed inside each triangle in the tessellation.
Applications of Triangular Tessellation
Triangular tessellation has various real-world applications, including:
- Art and Design: Tessellated patterns are commonly used in art, architecture, and interior design to create visually appealing and repetitive designs.
- Mathematics: Tessellation is used in geometry to explore the properties of shapes and patterns, as well as to understand symmetry and tiling.

Connections to the Grade 7 Focal Points (NCTM)
Number and Operations: In grade 4, students used equivalent fractions to determine the decimal representations of fractions that they could represent with terminating decimals. Students now use division to express any fraction as a decimal, including fractions that they must represent with infinite decimals. They find this method useful when working with proportions, especially those involving percents. Students connect their work with dividing fractions to solving equations of the form ax = b, where a and b are fractions. Students continue to develop their understanding of multiplication and division and the structure of numbers by determining if a counting number greater than 1 is a prime, and if it is not, by factoring it into a product of primes.
