The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
It's when you add up the exterior angles for an obtuse triangle.
The sum of all angles in any type of triangle equals 180'
the sum of any triangle is always 180 degrees...
acute, obtuse and right angles
yes
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.
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.
The triangle is an isosceles triangle.
180 degrees
Angle sum property of a triangle states that the sum of angles in any triangle should be 180 degree. An angle greater than 90 degree is an obtuse angle. If we have 2 obtuse angles in a triangle, say, 95 degree, 100 degree & 50, it always tend to violate the angle sum property of the triangle. So we cannot have 2 obtuse angles in a triangle.
