Find below the list of all AP Board Class 7th Maths Chapter 4 Lines and Angles Ex 4.3 Textbook Solutions for PDF’s for you to download and prepare for the upcoming exams:

Question 1.
Name three pairs of vertically opposite angles in the figure. If ∠AOB = 45°, then find ∠DOE.

Vertically opposite angles :
∠AOB, ∠DOE; ∠BOC, ∠EOF; ∠COD, ∠AOF
Given ∠AOB = 45°
In the given figure, ∠AOB is the vertically opposite angle to ∠DOE.
So, ∠DOE = ∠AOB = 45°
∴ ∠DOE = 45°

Question 2.
In the given figure 𝐏𝐐−→− is a straight line. Check whether x and y are vertically opposite angles or not. Give reason.

𝐏𝐐−→− is a straight line. But 𝐒𝐑−→ is not a straight line.
If 𝐏𝐐−→− and 𝐒𝐑−→ are intersecting lines the x and y become vertically opposite angles.
So, x and y are not vertically opposite angles.

Question 3.
Write any three examples for vertically opposite angles in your surroundings.
Scissors, window grills, cross roads, rail cross junctions, etc.

Question 4.
In the given figure, the lines l and m intersect at point P. Observe the figure and find the values of x, y and z.

Given l and m are intersecting lines at P.
∠y = 20° (vertically opposite angles)
∠x = ∠z (vertically opposite angles)
∠y + ∠x = 180° (linear pair)
⇒ 20° + ∠x = 180°
⇒ 20° + ∠x – 20° = 180°- 20
⇒ ∠x = 160°
∴ ∠x = ∠z = 160°
∠x = 160°, ∠y = 20° and ∠z = 160°.

Question 5.
In the given figure, two lines 𝐀𝐃←→ and 𝐄𝐂←→ intersects at O. Name two pairs of vertically opposite angles in the given figure.

In the given figure 𝐀𝐃←→ and 𝐄𝐂←→ are intersecting at O.
∠AOE = ∠COD (Vertically opposite angles)
∠1 = ∠3
∠EOD = ∠AOC (Vertically opposite angles)
∠EOD = ∠AOB + ∠BOC (we know ∠AOC = ∠AOB + ∠BOC)
∠2 = ∠5 + ∠4

Question 6.
Two lines 𝐏𝐒←→ and 𝐐𝐓←→ intersect at M. Observe the figure and find x.

In the given figure 𝐏𝐒←→ and 𝐐𝐓←→ are intersecting at M.
∠PMQ = ∠TMS (Vertically opposite angles)
∠QMS = ∠PMT (Vertically opposite angles)
∠QMR + ∠RMS = ∠PMT (we know ∠QMS = ∠QMR + ∠RMS)

But, given, ∠QMR = 40°, ∠RMS = x° and ∠PMT = 105°
⇒ 40° + x° – 40° = 105° – 40°
∴ x° = 65°
