120 degrees. Each interior angle of an equilateral triangle is 60 degrees, so each exterior angle is 180 - 60 = 120 degrees It can also be worked out by the formula Exterior angle of a polygon = 360/no. of sides of the polygon = 360/3 = 120
Each exterior angle measures 120 degrees and each interior angle measures 60 degrees because there are 180 degrees on a straight line.

Can an equilateral triangle have a right angle?
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
What is the measure of each angle in an acute equilateral triangle?
Each interior angle of an equilateral triangle measures 60 degrees
What is the angle of rotation for an equilateral triangle?
60 degrees, 120 degrees
How many degrees are there in each exterior angle of an equilateral triangle A 30 degrees B 60 degrees C 90 degrees D 120 degrees?
an interior angle + and exterior = 180 Angle A: 180-30=150 Angle B: 180-60=120 Angle C: 180-90=90 Angle D: 180-120=60 SO WHATS THE ANSWER!!!?????
What is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
What is the measure of an exterior angle of an equilateral triangle?
120 degrees.
Which of these two regular polygons has the larger exterior angle a triangle or a heptagon?
It is the equilateral triangle that has the largest exterior angle of 120 degrees
Which of these two regular polygons has the largest exterior angle heptagon or triangle .?
It is the regular equilateral triangle whose each exterior angle is 120 degrees
How many degrees are in the exterior angle of an equilateral triangle?
120 degrees x 3 = 360
What are exterior angles?
They equal the supplement of the interior angle it is adjacent to. (180-int. angle) E.g: the exterior angles of an equilateral triangle are each equal to 120 degrees.
What is the name of the regular polygon whose exterior angles are twice its exterior angles?
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
What is the sum of the measures of the exterior angles of a regular polygon if each exterior angle measures 120?
360 degrees and the polygon is an equilateral triangle.
Can an equilateral triangle have a right angle?
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
