The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
The sum of the interior angles of an obtuse triangle as with all triangles is 180 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 exterior sum of the angles of any polygon including a triangle is always 360 degrees.
You mean "two". No. The sum of 2 obtuse angles must be over 180 degrees, which exceeds the sum of the 3 angles of a triangle = 180 degrees.
No - not a plane triangle. The angles of a regular triangle must be equal. So an obtuse triangle, if regular, would have three obtuse angles. The sum of the angles would then be greater than 3*90 = 270 degrees. But the sum of angles of a triangle must be 180 degrees.
Exterior angles: 360 degrees Interior angles: 180 degrees
The sum of all angles in any type of triangle equals 180'
the sum of any triangle is always 180 degrees...
The exterior angles of a triangle add up to 360 degrees.
The sum of the 3 exterior angles of an equilateral triangle add up 360 degrees
