Step-by-step explanation:
Given,
to identify different views of a 3D objects.
But,
Assuming directly 3 dimension views of a object is quiet difficult, so now inorder to find out the different views let us take a lamp and try to analyse the shades of every particular geometry figure thus given
(i) circle.
so when light is focused on to the circle we get a view of a sphere as shown below in figure.
∴ The circle can we have different views like spherical or circular objects.
(ii)Trinagle:
when light is passed through triangle it looks like figure b
view of triangle when light is focused on to it.
Triangle can be viewed as a triangular prism.
∗ It can be viewed as a triangular shapes on right prism with triangular base.
(iii) square:
When light gets focused on to square it looks as figure.
the view of square when light is passed through it
∗ A square looks like a cube or square sheets.
(iv) Rectangle:
When light gets focused on to rectangle it looks as figure.
The view of rectangle will be as a cylinder when exposed to light.
∗ A rectangle looks like a cylinder or rectangular sheets.
