In geometry, what is the term for a triangle with one angle measuring more than 90 degrees?

A triangle with one angle measuring more than 90 degrees is defined as an obtuse triangle. In geometry, the classification of triangles based on their angles is quite specific. An obtuse triangle has one angle that exceeds a right angle (90 degrees), while the other two angles are acute, meaning they are each less than 90 degrees.

This specific property of having one angle greater than 90 degrees is what distinguishes obtuse triangles from other types of triangles. In contrast, an acute triangle has all angles measuring less than 90 degrees, while a right triangle has one angle exactly equal to 90 degrees. An equilateral triangle, on the other hand, has three equal angles of 60 degrees each, making it acute as well, but not obtuse. Thus, the correct terminology for a triangle with an angle that exceeds 90 degrees is obtuse triangle.
