Sample Questions

1multiple choice

If a point has coordinates (0, 0, 5), where does it lie?

Show answer

On Z-axis

When x = 0 and y = 0, the point lies on the Z-axis.

2multiple choice
1 marks

The direction cosines of the X-axis are:

Show answer

1, 0, 0

The X-axis makes 0° with X-axis and 90° with Y and Z axes. So cos0° = 1, cos90° = 0, 0.

3multiple choice

The projection of the point (4, 5, 6) on the XY-plane is:

Show answer

(4, 5, 0)

Projection on XY-plane means z = 0, so (4, 5, 0).

4multiple choice
1 marks

The distance between (1, 1, 1) and (4, 5, 6) is:

Show answer

7 units

Distance = √((4-1)² + (5-1)² + (6-1)²) = √(9 + 16 + 25) = √50 ≈ 7.07 ≈ 7 units.
