Interior Angles of a Triangle: 60 Exterior Angles of a Triangle: 120 Interior Angles of a Heptagon 128 (approx) Exterior Angles of A Heptagon 52 (approx) Answer: Triangle
It's when you add up the exterior angles for an obtuse triangle.
The exterior sum of the angles of any polygon including a triangle is always 360 degrees.
The exterior angles of a triangle add up to 360 degrees.
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
The interior angles of a triangle add up to 180 degrees. The exterior angles of a triangle add up to 360 degrees.
The sum of the interior angles of any triangle is 180 degrees.
The exterior angles of a triangle add up to 360 degrees.
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
