(5) Geometric patterns. The student uses a variety of representations to describe geometric relationships and solve problems. The student is expected to:

• (A) use numeric and geometric patterns to develop algebraic expressions representing geometric properties;

• (B) use numeric and geometric patterns to make generalizations about geometric properties, including properties of polygons, ratios in similar figures and solids, and angle relationships in polygons and circles;

• (C) use properties of transformations and their compositions to make connections between mathematics and the real world, such as tessellations; and

• (D) identify and apply patterns from right triangles to solve meaningful problems, including special right triangles (45-45-90 and 30-60-90) and triangles whose sides are Pythagorean triples.
