Question

in the following figure, if angle 2 =110' and angle 5=70'then prove that m//n​

Answer 1

Answer:

firstly angle 1 and angle 5 form the 180 angle

and angle 3 is equal to angle 5 by alternate interior angle so angle 2 and angle angle 3 also form 180 degree angle and angle 3 is also equal to angle 1

so therefore angle 1 is equal to angle 5 but they are corresponding angle hence we know that if corresponding angle are equal than 2 line are parallel

so m//n
