Question

Builder has made a layout of a colony so that lane a is parallel to
b? He also plans to leave green area as shown in the figure What
value is he showing by doing so? If measure of angle 1 is 120?,
find the measure of all other angles

Dear Student,
Solution:
Given: A∥B and ∠1=120°Now, Since ∠3 and ∠1 are on the same line, ∠1+∠3=180°So, ∠3=180°-120°=60°And ∠2=∠3=60° {Vertically opposite Angles}And ∠4=∠1=120°{Vertically opposite Angles}And ∠2=∠6=60°{Corresponding Angles}And ∠1=∠5=120°{Corresponding Angles}And ∠7=∠6=60°{Vertically opposite Angles}And ∠8=∠5=120°{Vertically opposite Angles}By leaving a portion of green area, the builder shows moral values towards the nature as he is willing to do plantation and preserve natural resources in the area
