An obtuse angle is any angle greater than 90 degrees and less than 180 degrees. Yes. An obtuse angle is geometrically greater that a right angle. Any number degree larger than â¦ 90 degrees is obtuse, as any number degree lesser than 90 degrees is acute.
Some triangles will have one angle that is exactly 90 degrees. Those are right triangles because one angle is 90 degrees. (The other two angles must be acute because they must add up to 90 degrees.) Some triangles will have one angle that is more than 90 degrees. Those are obtuse triangles because one angle is obtuse. (The other two angles are acute because the sum of the other two triangles is less than 90 degrees). Some triangles will have all three angles less than 90 degrees. Those are the acute triangles. Go ahead, start with a right triangle.
