7. But don’t get stressed out
But don’t get stressed out. Here are a few ways to remember which angle is which.
The letter “a” comes before the letter “o” in the alphabet. “a” for acute, represents a smaller angle (less than 90 degrees) than “o” for obtuse (an angle greater than 90 degrees)
The letter “r” for right triangle, represents an angle that can sit up right with one line straight out connected to another line straight up
