A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)

A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles

An acute triangle

Acute.Acute.Acute.Acute.

If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
