Types of shapes in maths12/28/2023 We use it to draw straight lines.Ĭurved line is a line in which both ends may or may not meet each other.Ī pattern is a series of items placed in a certain order. Straight line is a line in which both the ends never meet each other. Now if you hold it loosely, you get a curved line. Hold a thread and stretch it tightly, you get a straight line. A line is formed by placing many points next to each other.It is always named by a capital letter.A point has no shape, breadth, length or height. Cylinder: A cylinder has 3 faces, 2 edges and 0 corners.Cone: A cone has 2 faces, 1 edge and 1 corner.Sphere: A sphere has 1 face, 0 edges and 0 corners. Cuboid: A cuboid has 6 faces, 12 edges and 8 corners.Cube: A cube has 6 faces, 12 edges and 8 corners.In general, plane figures made of lines are known as polygons. Also, these figures can have any number of sides. Straight or curved lines make up the sides of this shape. In other words, a plane object that has only length and breadth is 2 dimensional. Shapes like cube, cuboid, cone, sphere and cylinder are called solid shapes. In geometry, a shape or a figure that has a length and a breadth is a 2D shape. Oval: An oval also has no corners and no sides.Circle: A circle has no corners and no sides.Rectangle: A rectangle has 4 corners and 4 sides.Square: A square has 4 corners and 4 sides.Triangle: A triangle has 3 corners and 3 sides.Shapes like circle, triangle, square, rectangle and oval are called flat or plane shapes. To be a regular polygon all the sides and angles must be the same: Triangle - 3 Sides. A polygon which has all the sides and angles as equal is called a regular polygon. Some common 2D shapes are squares, rectangles. It consists of a length and a width but does not have any depth or height. For example, a sheet of paper is two-dimensional in shape. Apart from the circle, all the shapes are considered as polygons, which have sides. A 2D shape is a flat shape that has only two dimensions - length and width, with no thickness or depth, that is the reason why it is called a two-dimensional shape. Solid shapes are called 3D shapes (Three dimensional shapes). A polygon is a 2D shape with straight sides. The basic types of 2d shapes are a circle, triangle, square, rectangle, pentagon, quadrilateral, hexagon, octagon, etc.Plane shapes are known as 2D shapes (Two dimensional shapes).So all other quadrilaterals are irregular. The only regular (all sides equal and all angles equal) quadrilateral is a square. and that's it for the special quadrilaterals. one of the diagonals bisects (cuts equally in half) the other.the diagonals, shown as dashed lines above, meet at.The KiteĮach pair is made of two equal-length sides that join up. (the US and UK definitions are swapped over!)Īn Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles. NOTE: Squares, Rectangles and Rhombuses are allĪ trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.Īnd a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides: A geometrical shape is a structure that has a definitive shape comprised of curves, lines, and/or points. Also opposite anglesĪre equal (angles "A" are the same, and angles "B" The ParallelogramĪ parallelogram has opposite sides parallel and equal in length. In other words they "bisect" (cut in half) each other at right angles.Ī rhombus is sometimes called a rhomb or a diamond. The RhombusĪ rhombus is a four-sided shape where all sides have equal length (marked "s").Īlso opposite sides are parallel and opposite angles are equal.Īnother interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. The SquareĪ square has equal sides (marked "s") and every angle is a right angle (90°)Ī square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The little squares in each corner mean "right angle"Ī rectangle is a four-sided shape where every angle is a right angle (90°).Īlso opposite sides are parallel and of equal length. Let us look at each type in turn: The Rectangle Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. From: A Maths Dictionary for Kids by Jenny Eather at Two-dimensional (2D) shapes are plane or flat shapes, having. A pizza is circular, whose slices are triangular. There are special types of quadrilateral: Some of the geometric shape examples are circle, rectangle, triangle, etc. They should add to 360° Types of Quadrilaterals Try drawing a quadrilateral, and measure the angles. interior angles that add to 360 degrees:.(Also see this on Interactive Quadrilaterals) Properties
