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.

AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 4
(i) If ∠QOR= 50°, then what is ∠POQ?
Answer:
Given ∠QOR= 50°
∠POQ, ∠QOR are linear pair.
⇒ ∠POQ + ∠QOR = 180°
⇒ ∠POQ + 50° = 180°
⇒ ∠POQ — 180° – 50° = 130°
.-. ∠POQ =130°

(ii) If ∠QOP = 102°, then what is ∠QOR?
. Sol. Given ∠QOP = 102°
∠QOP and ∠QOR are linear pair.
⇒ ∠QOP + ∠QOR = 180°
⇒ 102° + ∠QOR = 180°
⇒ 102°- 102° + ∠QOR = 180°- 102°
⇒ ∠QOR = 78°

Question 2.
Mahesh said that the sum of two angles 30° and 150° is 180°, hence they are linear pair. Do you agree? Justify your answer.
Answer:
No, sum of two angles is 180°, then they are said to be supplementary angles.
If the two angles are on the same straight line and they are adjacent they are said to be linear pair.
So, the two angles 30° and 150° are need not be linear pair.

Question 1.
In the adjacent figure, AB is a straight line, O is a point on AB. OC is a ray. Take a point D in the interior of ∠AOC, join OD.
Find ∠AOD + ∠DOC + ∠COB.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 6
Answer:
Given ∠AOC and ∠COB are linear pair. But ∠AOC = ∠AOD + ∠DOC
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 12
⇒ ∠AOC + ∠COB = 180° (linear pair)
⇒ ∠AOD + ∠DOC + ZCOB = 180°

Question 2.
In the given figure, AG is a straight line. Find the value of ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 13
Answer:
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.
If ∠3 = 116°, then what is ∠5?
Answer:
In the figure ∠5 = ∠3 (Alternate interior angles)
Given ∠3 = 116°
So, ∠5 = ∠3 = 116°
∴ ∠5 = 116°

Question 2.
If ∠4 = 51°, then what is ∠5?
Answer:
In the figure the interior angles in the same side of transversal are supple-mentary’.
So, ∠5 + ∠4 = 180° we know ∠4 = 51°
∠5 + 51° = 180°
∠5 + 51° – 51° = 180° – 51°
=> ∠5 = 129°

Question 3.
If ∠1 = 123° then what is ∠7?
Answer:
In the given figure
∠7 = ∠1 (Alternative exterior angles) Given ∠1 = 123°
So, ∠7 = ∠1 = 123°
∴ ∠7 = 123° .

If ∠2 = 66° then what is ∠7?
Answer:
In the given figure,
sum of the exterior angles are the same side of transversal are supplementary. So, ∠2 + ∠7 = 180°
=> 66° + ∠7 = 180° (Given ∠2 = 66°)
=> 66° + ∠7 – 66° = 180° – 66°
=> ∠7 = 114°
∴ ∠7 = 114°

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.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 20
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 = \(\frac{4}{9}\) × 180° = 80°
Second angle = \(\frac{5}{9}\) × 180 °= 100°

AP Board 7th Class Maths Solutions Chapter 4 Lines and Angles InText Questions

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° = \(\frac{180^{\circ}}{2}\)
∴ x° = 90°
Hence, each angle = 90°

Question 4.
In the given figure, PS is a straight line, find x°.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 21
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.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 22
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.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 23
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.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 24
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°

Question 8.
In the figure \(\overrightarrow{\mathbf{M N}} \| \overrightarrow{\mathbf{K L}}\) and \(\overline{\mathrm{MK}}\) is transversal. Find x.
AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 25
Answer:
From the figure, \(\overrightarrow{\mathbf{M N}} \| \overrightarrow{\mathbf{K L}}\) and \(\overline{\mathrm{MK}}\) 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 = \(\frac{150^{\circ}}{3}\)
∴ x = 50°

\(\overline{\mathrm{AB}} \| \overline{\mathrm{CF}}\) and \(\overline{\mathrm{BC}}\) is a transversal,
x + 103° = 180°
x = 180°- 103°
x = 77°

From the figure,
\(\overline{\mathrm{DC}} \| \overline{\mathrm{CF}}\) and \(\overline{\mathrm{CD}}\) is a transversal,
y + 103° = 180°
y = 180°- 103°
y = 77°
and ∠BCD = x + y = 77° + 77° = 154°

Question 10.

AP Board 7th Class Maths Solutions Chapter Chapter 4 Lines and Angles InText Questions 27
Answer:
In the given figure, it is given that each angle in the pair of corresponding angles is 45°. So they are equal. Since a pair of corresponding angles are equal the lines are parallel. Hence, m ∥ n.
