In an equilateral triangle, each exterior angle is _______
A. 60°
B. 90°
C. 120°
D. 150°
Answer :
In an equilateral triangle, each angle is of 60°.
Also, an exterior angle of a triangle is equal to the sum of the interior opposite angles.
⇒ Each exterior angle = 60° + 60° = 120°
Rate this question :
