The shapes can be classified based upon the dimensions they have.
A simple closed figure formed of three or more line segments is called a polygon. This means that these shapes have open ends and are not closed, for example, the letter C is an open shape as its ends do not meet.Ĭlosed Shapes – The shapes that are made of line segments that formed closed loops are called closed shapes.
Open Shapes – The shapes that are made of line segments that do not meet are called open shapes. whether those line segments form a closed loop or are open ended. Open and Closed ShapesĪs we have learnt, the first basic categorisation is based upon the nature of the line segments they are made of, i.e. Let us study these shapes in further detail. Therefore, based on the number of line segments, the shapes can be classified as – triangles, quadrilaterals, pentagon, hexagon etc.įurther, the shapes can be classified based upon the dimensions they have. For instance, we may need three line segments for a particular shape while another shape may need line segments. Next, we have the number of line segments that are required to form a shape. Based on the structure, the shapes are classified into two categories: whether those line segments form a closed loop or are open-ended. To start with it is important to understand how do we categorise different shapes? The first basic categorisation is based upon the nature of the line segments they are made of, i.e. The Sun, the earth and other planets, the mountains and all other things in the world are all of the specific shapes. The alphabets of English shapes are all shapes of different types. We come across many shapes in our daily lives and kids start recognising these shapes even before actually studying about them. The boundary or outline of an object is called its shape.
