Three Main Types of Angles. Acute-any angle which measures less than 90 degrees. These angles appear sharp, like the blade on a knife. Example: The angle ABC measures 40 degrees.Angle ABC is acute. Right-any angle which measures exactly 90 degrees. These are like the edges of a wooden block.Sample: The angle CAT measures 90 degrees. The angle CAT is a right angle. Obtuse-any angle which measures more than 90 degrees but less than 180 degrees. These are fat angles that are very wide.Sample: angle DEF measures 125 degrees.hree Main Types of Angles.
