Answer 2

See attachment for figure ↑

Step by step explanation :

=> Angle 4 + Angle 1 + Angle 5 = 180° ....{linear pair ( straight angle )}

Now,

=> Angle 4 = Angle 2 ......( alternate interior angles )

=> Angle 5 = Angle 3 .......( alternate interior angles )

Now,

If , Angle 4 + Angle 1 + Angle 5 = 180°

Therefore,

Angle 2 + Angle 1 + Angle 3 = 180°

Hence proved,

Sum of all interior angles of a triangle is equal to 180°
