Question

If the sides of a triangle are produced in order, Prove that the sum of the exterior angles so formed is 360°.

Answer 1

Suppose you have a ∆ABC
All the exterior angles will be equal to
(180-A)°
(180-B)°
(180-C)°
respectively (Angles on the same line) so if you sum it up it will be equal to 540 - (A+ B + C )
And by angle sum property A+B+C = 180°
Therefore Sum = 540 - 180 = 360
