State whether the statements are true (T) or false (F).

Triangle is a polygon whose sum of exterior angles is double the sum of interior angles.

TRUE

We know that,

Sum of Interior angles of Polygon = 180(n-2)
Sum of Exterior angles of Polygon = 360
Here, for triangle , n=3,ie. triangle

So, Sum of Interior angles of triangle = 180(n-2)° = 180(3-2)° = 180°

And ,Sum of Exterior angles of triangle = 360°

⸫ we can say that ,

2 × Sum of Interior angles of triangle = Sum of Interior angles of triangle

2 × 180° = 360°
