What is an obtuse triangle?
3 answers
An obtuse triangle is a triangle in which one of the angles measures more than 90 degrees. This means that one of the angles is "obtuse" and the other two angles are acute, meaning they measure less than 90 degrees.
So would a triangle on its side be obtuse?
No, a triangle on its side would not be considered an obtuse triangle. The classification of a triangle as obtuse, acute, or right is based on the measurement of the angles, not the orientation of the triangle. An obtuse triangle is one in which one of the angles within the triangle is greater than 90 degrees. If all three angles of a triangle measure less than 90 degrees, it would be considered an acute triangle. If one of the angles measures exactly 90 degrees, it would be a right triangle.
