INTRODUCTION TO DIFFERENT 3D SHAPES By: Engr.Irshad Rahim Memon

 To understand different 3d shapes

 Any geometrical shape of 3Dimensions (i.e. Length, breadth and Thickness), is called 3D Shape.

 A cone has a circular base, while the other end is a fixed vertex. The line from the centre of base to the fixed point is called Axis. If the axis is perpendicular to the base then the cone is Right Cone otherwise it is oblique Cone.

 A cube is a geometrical shape of 3 Dimensions, Length, width and height. All sides and angles of a cube are equal.

 A cylinder has two parallel circular surfaces joined together with lines. If the centre of both the circular faces is perpendicular then its Right Cylinder otherwise it’s Oblique Cylinder.

 A three dimension circular surface.

 Theory: A 3D shape having all sides and all angles equal.

 From Tools Bar take rectangle, check the dimensions at bottom of ms-paint, click and drag till the second dimensions bar shows 100x100.  Now draw another rectangle same way but from point 50x50. and join the angles / edges respectively.

 Draw a Cube of 300x300  Draw a Cube of 100x100  Draw a Cube of 500x500  Draw a Quadlateral of 300x300  Draw a Quadlateral of 400x400  Draw a Quadlateral of 500x500

 3D shapes of different Dimensions are verified
