can someone explain to me how you figure out if a triangle is obtuse, acute or a right angle? i will give 20 points

Right angle is 90 degrees, belowe 90 degrees is acute, and above 90 degrees is obtuse

Step-by-step explanation:

Right angle = 90degrees

Acute angle = <90degrees

Obtuse angle = >90degrees

To figure out if a triangle is obtuse, There would be one angle that is over 90 degrees. If it is an acute triangle, all of the angles would be smaller than 90 degrees. If it is a right triangle, there would be one angle that is 90 degrees and the other 2 angles would be acute.
