Find below the list of all AP Board Class 7th Maths Chapter 4 Lines and Angles Ex 7 Textbook Solutions for PDF’s for you to download and prepare for the upcoming exams:

Question 1.
Fill up the blanks
(i) The line which intersects two or more lines at distinct points is called __________
(ii) If the pair of alternate interior angles are equal then the lines are ______________
(iii) The sum of interior angles on the same side of the transversal are supplementary then the lines are ____________
(iv) If two lines intersect each other then the number of common points they have
Solution:
i) The line which intersects two or more lines at distinct points is called transversal.
ii) If the pairs of alternate interior angles are equal then the lines are parallel.
ii) The sum of interior angles on the same side of the transversal are supplementary then the lines are parallel.
iv) If two lines intersect each other then the number of common points they have Only one.

Question 2.
In the adjacent figure, the lines ‘P and ‘m’ are parallel and ‘n’ is a transversal. Fill in the blanks for all the situations given below.

(i) If ∠1 = 80° then∠2 =
(ii) If ∠3 = 45° then ∠7 =
(iii) If ∠2 = 90° then ∠8 =
(iv) If ∠4 = 100° then ∠8 =
Solution:
(i) If ∠1 = 80° then∠2 = 100
(ii) If ∠3 = 45° then ∠7 = 45
(iii) If ∠2 = 90° then ∠8 = 90
(iv) If ∠4 = 100° then ∠8 = 100

Question 3.
Find the measures of x,y and z in the figure, where l || BC

Solution:
∠y = 75° (alt. tnt. angles)
∠z = 45° (ait. tnt. angles)
∠x + ∠y + ∠z = 180° (∵ int. angles of a triangle = 1800)
75° + 45° + ∠x = 180°
∠x = 180°- 120°
= 60°

Question 4.
ABCD is a quadrilateral in which AB || DC and AD || BC. Find ∠b, ∠c and ∠d.
Solution:
∠b + ∠50° = 180° (int. angles on the same side of AB)
∠b = 180° – 50° = 130°
Similarly ∠b + ∠c = ∠c + ∠d = ∠d + ∠50 = 180°
∠130° + ∠c = 180°
∠c = 180° – 130° = 50°
Also ∠c + ∠d = 50° +∠d = 180°
∠d = 180° – 50° = 130°

Question 5.
In a given figure, ‘l’ and m’ are intersected by a transversal ‘n’. Is 1 || m?

Solution:
∠AQP and ∠CRS are exterior angles on the same side of the transversal n and their sum
100° + 80° = 180°
Hence l//m.

Question 6.
Find ∠a, ∠b, ∠c, ∠d and ∠e in the figure? Give reasons.

Note: Two anow marks pointing in the same direction represent parallel lines.
Solution:
∠a = ∠50° (∵ alt. int, angle between two parallel lines)
∠b = 50° (∵ alt. int, angle between two parallel lines)
∠b = ∠c = 50° (∵ alt. int. angles between two parallel lines)
∠c = ∠d = 50° ( ∵ alt. int angles between two parallel lines)
∠e = ∠d = 50°(∵ alt. int. angles between two parallel lines)
