Viewing an Object by Looking at It from Certain Angles to Get Different Views

A 3-dimensional object or shape look different from different positions (or sides), so they can
be drawn from different perspectives, this is called visualising a solid shape. One can look at an
object standing in front of it or by the side of it or from above. Each time, one will get a different
view. Let us see the different views of a house from different angles.

Here is an example that shows how one gets different views of the given building.

Sometimes when we look at combined shapes, some of them may be hidden from our view.
Let's take some cubes and arrange them as shown in fig. below.

Now we guess how many cubes are there when we observe the above fig. from different view
positions as we marked by the arrows?
