Answer 2

In an equilateral triangle, all three sides are equal in length, and all three angles are equal. Since the sum of the interior angles of any triangle is always 180 degrees, we can find the measure of each interior angle of an equilateral triangle by dividing 180 degrees by the number of angles, which in this case is 3.

Each interior angle of an equilateral triangle measures 60 degrees.

Now, to find the measure of each exterior angle of an equilateral triangle, we can use the fact that the sum of an interior angle and its corresponding exterior angle is always 180 degrees. Therefore, the measure of each exterior angle of an equilateral triangle is the difference between 180 degrees and the measure of each interior angle.

Each exterior angle of an equilateral triangle measures 120 degrees.

This means that if you were to extend one side of an equilateral triangle, the angle formed between that extended side and the adjacent side would measure 120 degrees.
