Polygons are plane figures made of straight line segments connected end to end to form a closed shape. The most common polygons in practice are triangles and quadrilaterals, but higher-order polygons like pentagons, hexagons, and octagons also appear in real-world structures. Understanding perimeter and area allows one to calculate boundaries and space covered, which has applications in construction, agriculture, engineering, and design.
1. Calculates and interprets perimeter and area of polygons that can be composed of triangles and quadrilaterals, including in real-world situations
Perimeter
- Perimeter is the distance around the outside of a polygon.
- For any polygon, the perimeter is simply the sum of all side lengths.
- For regular polygons (all sides equal): P = n × s, where n is the number of sides and s is the length of one side.
