Q.19 to Q.22 : Read the following paragraph and answer the questions given
below: 4X1=4
In a recent project, students of class XII created a tent for their school picnic. The
mathematical drawing is given below. They know that Isometric projection is a
powerful tool used in design and engineering to represent three-dimensional
objects on a two-dimensional surface with accuracy. So by utilizing isometric
drawings, they were able to create precise representations of the tent and
presented to Principal and teachers, who were impressed by the clarity and detail
provided.
