   3 days ago · Straight angles: A straight angle is an angle that measures exactly 180 degrees. Examples: Angle formed in a see-saw is a straight angle. A straight stick measures a straight angle. The flat surface of a ground measures a straight angle. Reflex angle: A reflex angle is an angle that measures greater than 180 degrees.
