Question 1.

Umesh said, “Two acute angles cannot form a pair of supplementary angles.” Do you agree ? Give reason.

Answer:

Yes, acute angle is always less than 90°. So, sum of two acute angles is always less than 180°.

Therefore, two acute angles cannot form a pair of supplementary angles (180°).

Question 2.

Lokesh said, “Each angle in any pair of complementary angles is always acute.” Do you agree? Justify your answer.

Answer:

Yes, sum of any two acute angles is 90°, then they are complementary angles. If they are not acute means they may . be right angle (90°) or obtuse angle (> 90°) or etc.

So, its impossible.

Therefore, each angle in any pair of complementary angles is always acute.

Given ∠AOC and ∠COG are linear pair. ∠AOC + ∠COG = 180° (linear pair)

But ∠AOC = ∠AOB + ∠BOC

= ∠1 + ∠2

∠COG – ∠COD + ∠DOE + ∠EOF + ∠FOG – ∠3 + ∠4 + ∠5 + ∠6

=> (∠AOB + ∠BOC) + (∠COD + ∠DOE + ∠EOF + ∠FOG)

= 180°

=> ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6

= 180°

Therefore, the sum of angles at a point on the same side of the line is 180°.

Question 1.

When a transversal intersects two lines and a pair of alternate exterior angles are equal, what can you say about the two lines?

Answer:

If a pair of alternate exterior angles are equal, then the two lines are parallel to each other.

Question 2.

When a transversal intersects two lines and a pair of co-exterior angles are supplementary, what can you say about the two-lines?

Answer:

If a pair of co-exterior angles are supplementary’ then the two lines are parallel to each other.

Examples:

Question 1.

In the given figure, ∠B and ∠E are complementary angles. Find the value of x.

Answer:

From the figure,

∠B = x + 10°and ∠E =35°

Since ∠B and ∠E are complementary angles,

∠B + ∠E =90°

⇒ x + 10° + 35° = 90°

⇒ x + 45° = 90°

⇒ x = 90°- 45°

x = 45°

Question 2.

If the ratio of supplementary angles is 4 : 5, then find the two angles.

Answer:

Given ratio of supplementary angles = 4:5

Sum of the parts in the ratio = 4 + 5 = 9

Sum of the supplementary angles = 180°

First angle = 49 × 180° = 80°

Second angle = 59 × 180 °= 100°

Question 3.

Find the linear pair of angles which are equal to each other?

Answer:

Let the equal linear pair of angles are x° and x°.

⇒ x° + x° = 180° .

⇒ 2x° = 180°

⇒ x° = 180∘2

∴ x° = 90°

Hence, each angle = 90°

Question 4.

In the given figure, PS is a straight line, find x°.

Answer:

From the given figure, ∠POQ = 60°

∠QOR = x°

∠ROS = 47°

But ∠POQ + ∠QOR + ∠ROS = 180°

⇒ 60° + x° + 47° = 180°

⇒ x° + 107° = 180°

⇒ x° = 180°- 107°

∴ x° = 73°

Question 5.

Observe the figure, then find x, y and z.

Answer:

From the figure, x = 110° (vertically opposite angles are equal)

y + 110° = 180°

y = 180°- 110° = 70°

z = y ⇒ z = 70°

Hence x = 110°, y = 70° and z = 70°

Question 6.

In the given figure AB ∥ CD and AE is transversal. If ∠BAC =120°, then find x and y.

Answer:

In the given figure, AB ∥ CD and AE is transversal.

∠BAC = 120

∠ACD = x

∠DCE = y

∠BAC = ∠DCE (correpsonding angles are equal)

y = 120°

x + y = 180 ° (Linear pair of angles are supplementary)

x + 120° – 180°

x = 180°- 120°

∴ x = 60°

Hence x = 60°, y =120°.

Question 7.

In the given figure, BA ∥ CD and BC is transversal. Find x.

Answer:

In the given figure, BA ∥ CD and BC is transversal.

∠C = x + 35° and ∠B = 60°

∠C = ∠B (∵ alternate interior angles are equal)

x + 35° = 60° .

x – 60° – 35°

∴ x = 25°

In the figure 𝐌𝐍−→−‖𝐊𝐋−→− and MK⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ is transversal. Find x.

Answer:

From the figure, 𝐌𝐍−→−‖𝐊𝐋−→− and MK⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ is transversal.

∠M = 2x and ∠K = x + 30°

∠M + ∠K = 180° (Q co-interior angles are supplementary)

⇒ 2x + x + 30° = 180°

⇒ 3x + 30° = 180°

⇒ 3x = 180° – 30°

⇒ 3x = 150° ⇒ x = 150∘3

∴ x = 50°

Question 9.

In the figure AB⎯⎯⎯⎯⎯⎯⎯⎯‖DE⎯⎯⎯⎯⎯⎯⎯⎯ and C is a point in between them. Observe the figure, then find x, y and ∠BCD.

Answer:

x = 77°

From the figure,

DC⎯⎯⎯⎯⎯⎯⎯⎯‖CF⎯⎯⎯⎯⎯⎯⎯ and CD⎯⎯⎯⎯⎯⎯⎯⎯ is a transversal,

y + 103° = 180°

y = 180°- 103°

y = 77°

and ∠BCD = x + y = 77° + 77° = 154°

Question 10.

In the figure transversal p intersects two lines m and n. Observe the figure, check whether m ∥ n or not.
