a) X-axis

b) Y-axis

c) Z-axis

d) X-Y plane

View Answer

Explanation: In 3d coordinate system, a point with x and y coordinate zero and z-coordinate having non-zero value must lie on z-axis. So, (0, 0, 3) lie on z-axis.

3. The point (0, 2, 0) lie on _________

a) X-axis

b) Y-axis

c) Z-axis

d) X-Y plane

View Answer

Explanation: In 3d coordinate system, a point with x and z coordinate zero and y-coordinate having non-zero value must lie on y-axis. So, (0, 2, 0) lie on y-axis.

4. The point (0, 2, 4) lie on _________

a) X-Y plane

b) Y-Z plane

c) X-Z plane

d) X-axis

View Answer

Explanation: In 3d coordinate system, a point with x-coordinate zero and y & z coordinate having non-zero value must lie on Y-Z plane. So, (0, 2, 4) lie on Y-Z plane.

5. The point (4, 2, 0) lie on _________

a) X-Y plane

b) Y-Z plane

c) X-Z plane

d) X-axis

View Answer

Explanation: In 3d coordinate system, a point with z-coordinate zero and x & y coordinate having non-zero value must lie on X-Y plane. So, (4, 2, 0) lie on X-Y plane.

6. The point (3, 0, 4) lie on _________

a) X-Y plane

b) Y-Z plane

c) X-Z plane

d) X-axis

View Answer

Explanation: In 3d coordinate system, a point with y-coordinate zero and x & z coordinate having non-zero value must lie on X-Z plane. So, (3, 0, 4) lie on X-Z plane.

7. Find the distance of point (2, 3, 5) from X-Y plane.

a) 2 units

b) 3 units

c) 5 units

d) 1 unit

View Answer

Explanation: We know, distance of a point from X-Y plane is equal to the value of its z-coordinate.

So, distance of point (2, 3, 5) from X-Y plane is 5 units.

8. Find the distance of point (2, 3, 5) from Y-Z plane.

a) 2 units

b) 3 units

c) 5 units

d) 1 unit

View Answer

Explanation: We know, distance of a point from Y-Z plane is equal to the value of its x-coordinate.

So, distance of point (2, 3, 5) from Y-Z plane is 2 units.

9. Find the distance of point (2, 3, 5) from X-Z plane.

a) 2 units

b) 3 units

c) 5 units

d) 1 unit

View Answer

Explanation: We know, distance of a point from X-Z plane is equal to the value of its y-coordinate.

So, distance of point (2, 3, 5) from X-Z plane is 3 units.

10. 2-D geometry has ______________ quadrants.

a) 1

b) 2

c) 4

d) 8

View Answer

Explanation: 2-D geometry can have 2 coordinates each with positive or negative value.

Total quadrants = 2*2 = 4.

11. 3-D geometry has ______________ octants.

a) 1

b) 2

c) 4

d) 8

View Answer

Explanation: 3-D geometry can have 3 coordinates each with positive or negative value.

Total octants = 2*2*2 = 8.

12. In which octant does the point (1, 5, 7) lies?

a) 1^{st}

b) 2^{nd}

c) 6^{th}

d) 7^{th}

View Answer

Explanation: Since the point with all positive coordinates i.e. of the form (+, +, +) so lie in 1

^{st}octant.

So, (1, 5, 7) lies in 1

^{st}octant.

13. In which octant does the point (-1, – 5, -7) lies?

a) 1^{st}

b) 2^{nd}

c) 6^{th}

d) 7^{th}

View Answer

Explanation: Since the point with all negative coordinates i.e. of the form (-, -, -) lie in 7

^{th}octant.

So, (-1, – 5, -7) lies in 7

^{th}octant.

14. In which octant does the point (-1, 5, 7) lies?

a) 1^{st}

b) 2^{nd}

c) 6^{th}

d) 7^{th}

View Answer

Explanation: Since the point with only x coordinate negative i.e. of the form (-, +, +) lie in 2

^{nd}octant.

So, (-1, 5, 7) lies in 2

^{nd}octant.

15. In which octant does the point (-1, 5, -7) lies?

a) 1^{st}

b) 2^{nd}

c) 6^{th}

d) 7^{th}

View Answer

Explanation: Since the point with only y coordinate positive i.e. of the form (-, +, -) lie in 6

^{th}octant.

So, (-1, 5, -7) lies in 6

^{th}octant.
