Question

I have a tumbler. What shape do I see if I look at the tumbler from its left or right side? What shape do I see if I look at the tumbler from the top? Discuss briefly about both these

Answer 1

The side view of the tumbler is shown in the above diagram. We can see that the figure is a simple closed curve made up of only line segments. So it is a polygon. Since it has 4 sides, it is a quadrilateral.

In quadrilateral, we can that 2 sides AB and CD are parallel, but other 2 sides are not. Hence, the figure is a trapezium.

When a tumbler is looked at from top, the above figure is visible. This figure is also a simple closed curve. But it is not made of any line segments. So, it is not a polygon. It is figure known as circle.
