A triangle on a concave surface.
An obtuse triangle
It is an obtuse scalene triangle.
An obtuse or a scalene triangle would have angles of the given sizes
An obtuse triangle is a triangle whos angle measure is greater than 180. The length of the sides of a scalene triangle are all different.
acute , obtuse obtuse or right angle
No because the 3 interior angles of any triangle add up to 180 degrees and 2 obtuse angles would measure over 180 degrees
Because the measure of 2 obtuse angles would be over 180 degrees and the measure of the 3 interior angles of a triangle must not be more than 180 degrees.
Yes
It is a triangle in which one of the angles has a measure in the range (90, 180) degrees.
An obtuse angled triangle.
It's when you add up the exterior angles for an obtuse triangle.
