"WebAn obtuse triangle is a triangle in which one of the interior angles is greater than 90°. It has one of its vertex angles as obtuse and other angles as acute angles i.e. when one angle measures more than 90°, the sum of the other two angles is less than 90°. An obtuse triangle can also be called an obtuse-angled triangle. " - Trig on triangles
