Question

sum of three exterior angle of a traingle is​

Answer 1

Step-by-step explanation:

the sum of three exterior angles of a triangle is 360°

If we take this concept on the bases of an equilateral triangle then,

In equilateral triangle each interior angle measures 60°

I think you might be already knowing that sum of the interior angles of a triangle is 180°

In the case of an equilateral triangle one exterior angle always measures 120°

because, the measure of one exterior angle of a triangle will be always equal to the sum of interior opposite angles

Since every angle measures 60° in an equilateral triangle ,the sum of 2interior angles is

60°+60°= 120°

so,

If one angle measures 120° then

120°+120°+120°=360°

the three of them will add upto 360°

Hope this might help you
