Describing Triangles
In the given diagram, we can see that one of the angles of the triangle has a measure of
Since is greater than and less than the angle is obtuse. If a triangle has an obtuse angle, it is an obtuse triangle.
In the given diagram, we can see that one of the angles of the triangle has a measure of 120∘.
Since 120∘ is greater than 90∘ and less than 180∘, the angle is obtuse. If a triangle has an obtuse angle, it is an obtuse triangle.
