The sum of the interior angles of a triangle on a plane is always 180 degrees.
Each exterior angle measures 120 degrees
(number of sides) - (2) times (180) = sum of interior angle measurements so for a triangle it is 3-2 which is 1 times 180 = 180, so the answer is 180 degrees
An interior angle is any angle on the interior of the triangle.
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.
Assuming you are referring to a triangle and are asking for one of the interior angle's measurements, this is the answer.Because it is an equilateral triangle, the measures of the 3 angles are the same. They add up to 180 by the interior angles theorem.Thus, the measure is 60 for each angle.

Exterior angle.
exterior angle theorem
(number of sides) - (2) times (180) = sum of interior angle measurements so for a triangle it is 3-2 which is 1 times 180 = 180, so the answer is 180 degrees
The 3 interior angles of any triangle add up to 180 degrees
In any triangle exterior angle plus interior angles = 180 degrees
An interior angle is any angle on the interior of the triangle.
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.
The shape is a triangle.
