The sum of the interior angles of a triangle on a plane is always 180 degrees.
Each exterior angle measures 120 degrees
An interior angle is any angle on the interior of the triangle.
(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
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.
The sum of the interior angles of a triangle on a plane is always 180 degrees.
Each interior angle of an equilateral triangle measures 60 degrees
Each exterior angle measures 120 degrees
Exterior angle.
exterior angle theorem
An interior angle is any angle on the interior of the triangle.
The 3 interior angles of any triangle add up to 180 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
In any triangle exterior angle plus interior angles = 180 degrees
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
