Understanding the difference between the area and the perimeter of a polygon is crucial. This simple yet essential concept is fundamental in many areas of mathematics and is particularly crucial in subjects like geometry and algebra.ĭifference Between Area and Perimeter of a Polygon

The more sides a polygon has, the more additions you’ll have to do to find the total perimeter. The perimeter of a polygon can be found by adding up the lengths of all its sides. In other words, the perimeter gives you the ‘boundary length’ of a polygon. It’s the equivalent of taking a piece of string, laying it along each side of the polygon, and then measuring the length of that string. The perimeter of a polygon, on the other hand, is the total distance around its edges or sides. The term originates from the Greek words ‘poly,’ meaning ‘many,’ and ‘gonia,’ meaning ‘angle.’ Hence, a polygon is a shape with many angles.

So let’s unravel the mystery of the ‘perimeter’ together, and remember, at Brighterly, we transform learning into a joyful journey! What is the Perimeter of a Polygon?Ī polygon is a 2-dimensional geometric shape with straight, non-intersecting sides. It’s an intriguing concept that has wide applications, from designing a soccer field to creating a blueprint for a house. All the while, our friend, the string, remains faithful, helping us trace the perimeter, whether the sides are equal (as in regular polygons) or varied (as in irregular polygons). Regular and irregular polygons have their unique ways of determining the perimeter. So, in essence, the perimeter of a polygon is the total distance around its sides.īut wait, it gets more interesting when we dive into different kinds of polygons. It’s like a path you would take if you were to walk around the edges of a garden or a park. Whether it’s a triangle, a square, or a complex dodecagon, that string follows their sides, defining the boundary of these shapes. That string, my friends, represents the perimeter of that shape. Now imagine, if you will, a string that we lay along the edges of a shape. We’re going to explore a fundamental aspect of polygons – their perimeters.

Knowledge of shape properties will include angles and symmetry of these polygons.Ĭhildren will describe shapes and identify them using their properties including symmetry and angles. They might be asked to sort shapes according to their properties using Venn diagrams and Carroll diagrams.Ĭhildren are taught to compare lengths and angles of polygons to decide if they are regular or irregular. The vocabulary ‘polygon’, ‘regular’ and ‘irregular’ will be used.Ĭhildren will be given a range of polygons to sort into regular and irregular this might be be completing practical tasks or using ICT.Ĭhildren will be taught to distinguish between regular and irregular polygons based on reasoning about equal sides and angles.Ĭhildren will be given shapes to sort and asked to explain why the polygon is regular using the properties of angles and sides.Īt the end of KS2 children begin to find unknown angles in regular polygons.Ĭhildren will be shown how to calculate unknown angles in polygons using their knowledge of angles and a given formula.Let’s dive into an adventurous journey exploring the fascinating world of polygons! Here at Brighterly, we believe in making learning fun and effective. They will be introduced to heptagons, nonagons and decagons. What is the shape?Ĭhildren will extend their knowledge of polygons to include different types of triangles and quadrilaterals. They will describe shapes using the properties, for example: This shape has 3 corners and 3 sides. They will look at real-life examples of shapes as well as pictures.Ĭhildren will be taught to identify properties of shapes such as the number of sides and vertices (corners).Ĭhildren will count the number of sides and corners on the shape. Children are taught to name common 2D shapes including polygons such as squares, rectangles, triangles, pentagons, hexagons and octagons.Ĭhildren may learn the shapes through matching activities, going on a shape walk in the school grounds, flash-cards and games.
