When discussing angles in geometry, one fundamental concept to understand is the notion of antonyms of acute angles. An acute angle is defined as an angle that measures less than 90 degrees. Therefore, the antonyms of acute angles are angles that measure 90 degrees or more.
Right angles are the most common example of antonyms of acute angles. A right angle measures exactly 90 degrees and forms a perfect L shape. This type of angle is crucial in geometry and is often used as a reference point in various geometric constructions and calculations.
Obtuse angles are another example of antonyms of acute angles. An obtuse angle is defined as an angle that measures more than 90 degrees but less than 180 degrees. These angles appear wider and more open than acute angles, providing a contrast in geometric properties and applications.
