Which term describes a triangle with one angle greater than 90 degrees?

• A. Obtuse Triangle
• B. Right Triangle
• C. Fillet
• D. Inscribe

Answer: (A)

An obtuse triangle describes a triangle with one angle greater than 90 degrees. This classification comes from recognizing how angles in a triangle are measured: if all angles are less than 90, the triangle is acute; if one angle is exactly 90, it is a right triangle; and if one angle exceeds 90, the triangle is obtuse. The other terms don’t describe triangle angle types: a right triangle has a 90-degree angle, a fillet refers to a rounded corner in design, and to inscribe means to fit a figure inside another shape, not to classify a triangle by its angles.
