Let us look at a few of the most commonly seen 3D shapes.Ī sphere is round and circular in shape. In mathematics and real life, there are many 3D shapes and objects with different bases, surface areas and volumes. Understand the concept of Polyhedron here in detail. Examples of 3D ShapesĬuboid, cube, cylinder, sphere, pyramid and cone are a few examples of 3D shapes 3D shapes occupy space. In a world with three dimensions, you can travel forward, backward, right, left, and even up and down. Thus they have three dimensions and so are known as 3D shapes. One thing common in these objects is that they all have some length, breadth and height or depth. In our day to day life, we see several objects around us which have different shapes. For example, books, balls, ice-cream cones etc. 3D ShapesĪ three-dimensional shape is defined in geometry as a solid figure or an item or shape with three dimensions - length, breadth, and height. Interior angles add up to 1260°.Ī 10-sided shape is called a Decagon. Interior angles add up to 1080°.Ī 9-sided shape is called a Nonagon. Interior angles add up to 900°.Īn 8-sided shape is called an Octagon. Interior angles add up to 720°.Ī 7-sided shape is called a Heptagon or Septagon. Interior angles add up to 540°.Ī 6-sided shape is called a Hexagon. The sum of the triangle’s three interior angles is 180°.Īn equilateral triangle is a regular triangle with 60° angles each.Īny triangle with one right angle is referred to as a right-angled triangle.Ī scalene triangle is an irregular triangle wherein every side and angle is unique.Īn isosceles triangle has two equal sides and two equal angles.Ī square is a regular quadrilateral with all vertices at 90° angles.Ī kite has two sets of equal-length sides, with diagonals intersecting at right angles.Ī rectangle is made up of two parallel straight lines, each with a 90° angle.Ī rhombus is defined by two parallel lines, equal sides, and opposite equal angles.Ī trapezium has one parallel pair of lines.Ī parallelogram is made up of two parallel lines and two opposite equal angles.Ī 5-sided shape is called a Pentagon. The entire arc has a 180° angle.Ī triangle is a closed polygon with three sides, three vertices, and three angles. The curved line’s points are at equal distances from its centre.Ī semi-circle has two sides, one curved and one straight. Let us look at a few of them and their properties.Ĭircles are entirely round shapes formed by a single curved line. Regular and irregular 2D shapes include the circle, triangle, square, rectangle, pentagon, and hexagon.
