If the sum is not 180° you are not in Euclidean space.If the three angles of a triangle add up to more than 180° then you are in a spherical space, if the sum is less than 180° it is a hyperbolic space.The internal angles of a planar (Euclidean) triangle always add up to 180 degrees.
The Interior angles of a triangle add up to 180° The Exterior angles of a triangle (or any other polygon) add up to 360°.
There are 3 angles in a triangle and they add up to 180 degrees
Sum of angles in a triangle is 180
The angles of any triangle add up to 180 degrees.
No because the 3 interior angles of a triangle add up to 180 degrees
There are 3 interior angles in a triangle and they add up to 180 degrees
No - the interior angles of a triangle add up to 180°.
The 3 interior angles of a triangle add up to 180 degrees
The angles of a triangle add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
The sum of the angles of a triangle MUST add up to 180o.
