The word “obtuse” is an adjective that describes someone or something as lacking in intelligence or being slow to understand. It can also refer to an angle greater than 90 degrees but less than 180 degrees.
Interesting fact: In geometry, an obtuse angle is often contrasted with an acute angle, which is less than 90 degrees. The term “obtuse” comes from the Latin word “obtusus,” meaning “blunt” or “dull.”
