Final answer:
In mathematics, acute, right, obtuse, and straight angles are important for understanding angles and geometry.
Step-by-step explanation:
In mathematics, the distinctions between acute, right, obtuse, and straight angles are important for understanding angles and geometry.
- An acute angle is an angle that is less than 90 degrees.
- A right angle is an angle that is exactly 90 degrees.
- An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees.
- A straight angle is an angle that is exactly 180 degrees.
