Question

Exercise 3.3
1. Find all the angles in the following figure ​

Answer 1

Answer:

$\blue { \angle a = \angle c = \angle e = \angle g = 135\degree }$

$\pink { \angle b = \angle d = \angle f= \angle h = 45\degree }$

Step-by-step explanation:

If AB //CD , PQ is a transversal.

$\angle e + \angle f = 180\degree$

$\blue { (Linear \: pair )}$

$\implies 135\degree + \angle f = 180\degree$

$\implies \angle f = 180\degree - \angle 135\degree \\= 45\degree$

$\angle e = \angle a = 135\degree$

$\orange {( Corresponding \:angles )}$

$\angle f = \angle b = 45\degree$

$\orange {( Corresponding \: angles )}$

$\angle e = \angle g = 135\degree$

$\angle f = \angle h = 45\degree$

$</p><p>[tex] \pink { ( Vertically \: opposite \:angles )}$

$</p><p>[tex] \angle a = \angle c = 135\degree$

$</p><p>[tex] \pink { ( Vertically \: opposite \:angles )}$

$</p><p>[tex] \angle b = \angle d = 135\degree$

$</p><p>[tex] \pink { ( Vertically \: opposite \:angles )}$

$</p><p>Therefore.,</p><p>[tex] \blue { \angle a = \angle c = \angle e = \angle g = 135\degree }$

$\pink { \angle b = \angle d = \angle f= \angle h = 45\degree }$
