Question

prove that the sum of the three exterior angles of a triangle is 360°​

Answer 1

Answer:

Suppose we take an equilateral triangle

Triangle PQR is an equilateral triangle

Thus, Angle P= angle Q= Angle R= 60°------(angles of an equilateral triangle).

So, angle P+angle O(exterior angle)=180° ----(linear pair angles)

= 180-60=120°

Similarly we prove all angles 120°

Addition will be 120+120+120=360°

Hope that helps.
