Question 1.
What do you think is the projection of a parallelogram under different orientations? Class 8
Can this ever be a quadrilateral that is not a parallelogram?
Solution:
It may be a parallelogram, rhombus, rectangle, square, trapezium, triangle and a line-segment.
The projection of a pair of parallel lines onto any plane is another pair of parallel lines. When they are projected on a plane perpendicular to them, they appear as two points having the same distance as the distance between those parallel lines itself.
Question 2.
What can you say about the projection of an n-sided regular polygon? Class 8
[Hint: Projection of a polygon is composed of the projections of its sides.]
Solution:
It may be an irregular n-sided polygon, a regular polygon itself, a line-segment or even a 12-sided polygon.
Question 3.
Observe the front view, top view and side view of the different lines. Is there any relation between their lengths? Class 8
Solution:
There appears to be no relation between their lengths.
