Access Important Questions for Class 6 Maths Ganita Prakash Chapter 2 Lines and Angles

1. What is the name of an angle that measures exactly 90°?

Ans: An angle that measures exactly 90° is called a right angle.

2. Identify the type of angle if it measures between 90° and 180°.

Ans: An angle that measures between 90° and 180° is called an obtuse angle.

3. How many degrees are there in a complete rotation around a point?

Ans: A complete rotation around a point measures 360°.

4. What is the sum of two complementary angles if one of the angles is 35°?
Ans: The sum of complementary angles is always 90°.
Let the other angle be xxx.
So, x + 35° = 90°
x = 90° − 35° = 55°
Therefore, the other angle is 55°.

5. What is the measure of each angle if two angles are supplementary and one of them is 110°?
Ans: The sum of supplementary angles is always 180°.
Let the other angle be y.
So, y + 110° = 180°
y = 180° − 110° = 70°
Therefore, the other angle is 70°.

6. Two angles are vertically opposite. If one of the angles is 45°, what is the measure of the other angle?
Ans: Vertically opposite angles are equal.
So, if one angle is 45°, the other vertically opposite angle is also 45°.

7. Define adjacent angles.

Ans: Adjacent angles are two angles that have a common vertex and common arm but do not overlap. They lie next to each other.

8. Find the angle measure if an angle is twice its complement.
Ans: Let the angle be xxx and its complement be 90° − x
According to the question, x =2 $\times$ (90° - x)
Solving:
x = 180° − 2x
3x = 180°

x = 60°

So, the angle is 60°, and its complement is 30°.

9. What is the measure of each angle if two angles are complementary and equal?

Ans: Let each angle be x. Since they are complementary, x + x = 90°.

So, 2x = 90°, x = 45°.

Therefore, each angle measures 45°.

10. If two angles are in the ratio 2:3 and are supplementary, find the measures of the angles.
Ans: Let the angles be 2x and 3x.
Since they are supplementary, 2x + 3x = 180°
5x = 180°
x = 36°
The angles are 2x = 2 $\times$ 36° = 72° and 3x = 3 $\times$ 36° = 108°.
So, the angles are 72° and 108°.

11. An angle is 30° less than its supplement. Find the angles.
Ans: Let the angle be xxx and its supplement be 180° − x.
According to the question, x = (180° − x) − 30°.
Solving:
x + x = 150°
2x = 150°
x = 75°
So, one angle is 75° and the other is 180° − 75° = 105°.
The angles are 75° and 105°.

12. If one angle of a linear pair is 75°, what is the measure of the other angle?

Ans: In a linear pair, the sum of the angles is 180°.

So, the other angle is 180° − 75° = 105°.

Thus, the measure of the other angle is 105°.

13. Find the angle which is equal to its own complement.
Ans: Let the angle be x.
Since it’s equal to its complement, x + x = 90°.
2x = 90°
x = 45°
So, the angle is 45°.

14. If two lines intersect and one of the angles formed is 120°, what are the measures of the other three angles?
Ans: When two lines intersect, they form two pairs of vertically opposite angles.
If one of the angles is 120°, the angle vertically opposite to it is also 120°.
The other two angles are supplementary to 120°, so each will be 180° − 120° = 60°.
Thus, the four angles are 120°, 120°, 60°, and 60°.

15. If two angles are supplementary and one of them is 35° more than the other, find the angles.

Ans: Let the smaller angle be x; the larger angle is x + 35°.

Since they are supplementary:

x + (x+35°) = 180°

2x = 145°

x = 72.5°

Therefore, x + 35° = 72.5° + 35° = 107.5°

The angles are 72.5° and 107.5°.

16. An angle is 40° more than its complement. Find the angles.
Ans: Let the angle be xxx and its complement be 90° − x.
According to the question, x = (90°−x) + 40°.
Solving:
2x=130°2x = 130°2x=130°
x=65°x = 65°x=65°
So, the angle is 65° and its complement is 90°−65°=25°90° - 65° = 25°90°−65°=25°.
The angles are 65° and 25°.

17. Name an example of perpendicular lines in daily life.

Ans: An example of perpendicular lines in daily life is the intersection of the edges of a notebook (where the horizontal and vertical edges meet at right angles).

18. Find the angles if two angles are in the ratio 3:7 and are supplementary.
Ans: Let the angles be 3x and 7x.
Since they are supplementary, 3x + 7x = 180°.
10x = 180°

x =18°
The angles are 3x = $ \times$ 18° = 54° and 7x = 7$ \times $18° = 126°.
So, the angles are 54° and 126°.

19. What is the measure of the angle formed by the hands of a clock at 3 o’clock?

Ans: At 3 o’clock, the minute hand is at 12, and the hour hand is at 3, forming a right angle.

Therefore, the angle formed is 90°.

20. If two angles are in the ratio 4:5 and form a linear pair, find the measures of the angles.

Ans: Let the angles be 4x4x4x and 5x5x5x. Since they form a linear pair, their sum is 180°.

So, 4x + 5x = 180°

9x = 180°

x = 20°

The angles are 4x = 4 $\times $20° = 80° and 5x = 5 $\times $20° = 100°.

Thus, the angles are 80° and 100°.
