A rectangle has two pairs of parallel sides.

RectangleĪ rectangle is a type of quadrilateral that has equal opposite sides and four right angles. Let us now learn about different types of quadrilaterals. All the quadrilaterals have two diagonals.The sum of the four angles of the quadrilateral is 360 o.All the quadrilaterals have four vertices.All the quadrilaterals have four angles.All the quadrilaterals have four sides.But, there are some properties of quadrilaterals that apply to all irrespective of their unique properties. This quadrilateral cannot be named as ABDC as the vertices B and D are not adjacent.Īlso, all the quadrilaterals have the same number of sides and angles, there may be a difference in the measurement of these sides and angles due to which we have different types of quadrilaterals. For example, in the below figure, ABCD, the vertices are A, B, C and D. For example, the shapes such as cube and cuboid are 3-dimensional shapes. Vertex– The meeting point of a pair of sides of a polygon is called its vertex. For example, the shapes such as rectangles and squares are 2-dimensional shapes.ģD shapes – 3 Dimensional shapes or 3D shapes are the shapes that have all the three dimensions, i.e. The three dimensions are length, breadth and height.ĢD shapes – 2 Dimensional shapes or 2D shapes are the shapes that have only length and breadth. 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.
