  1. 1. Maths presentation directed by AISHWARYA VIII B 01
  2. 2. introduction We have learnt about plane shapes and solid shapes. Plane shapes have two measurements like length and breath and therefore they called two dimensional shapes. Whereas a solid object has two measurements like length , breath, height, or depth. Hence, they are called three dimensional shapes.Two dimensional object Three dimensional object
  3. 3. A solid object occupies some space. Two dimensional andThree- dimensional figures can also be briefly named as 2-D and 3-D figures. You may recall that triangle, rectangle,circle etc., are 2-d figures while cubes, cylinders, cones,spheres etc. are 3-Dimentional figures. name of shape type of shape shape 2-Dimensional Square 3-Dimensional Cone 3-dimensional Cylinder 2- Triangle dimensional 3-dimensional Cube 2-Dimensional Circle 3-Dimensional Cuboid 3-Dimensional Sphere
  4. 4. A tent. A cone A tin. A cylindrical surmounted on a shell. Softy(ice-cream). A cylinder. cone surmounted by a hemisphere. A photoframe . A A boul. A hemispherical shell. Tomb on a pillar. rectangular path. Cylinder surmounted by a hemisphere.Note that all the above shapes are single. However, in ourpractical life, many a times, we come across combinationsof different shapes. For example, look at the above objects.
  5. 5. views of 3-D shapesA Groove A circular path around a circular ground.A toy A rectangular field adjoining a square field.A circular A cone taken out of a cylinder.park A cross path A hemisphere surmounted on a cone.
  6. 6. We have learnt that a 3-dimensional object can lookdifferently from different positions so they can be drawnfrom different perspectives. For example, a given hut canhave the following views. Top front side hut Top View Side ViewFront View
  7. 7. Similarly, a glass can have the following views. A Glass Side View Top View
  8. 8. Why is the top view of the glass a pair of concentric circles?Will the side view appear different if take from some otherdirection? Think about this! Now look at the different views ofa brick. A Brick Side view Top View Front View
  9. 9. We can also get different views of figures made by joiningcubes. For example.Solid made of Top view Side view. Front viewthree cubes.Solid made up of Front view. Side view. Top view four cubes. Side view. Front view. Top view. Solid made of four cubes.
