Which type of angle is greater than 90 degrees but less than 180 degrees?

Explanation:
When we classify angles by size, we look at their degree measure. An angle larger than a right angle but less than a straight angle is called obtuse. A right angle is exactly 90 degrees, and a straight angle is exactly 180 degrees, so anything strictly between those two is obtuse. An acute angle is too small (less than 90), and a straight angle is too large (180). Picture an angle opened wider than a right angle but not all the way to a straight line—that’s obtuse.
