Angles that measure less than a right angle?
anythin between 0 degrees and 90 degrees (called acute angles)
What angles measures greater than 90 degrees and less than 180 degrees?
obtuse angles
What is the difference between acute right and obtuse angles?
Acute angles are greater than zero and less than 90 degrees. Right angles are exactly 90 degrees. Obtuse angles are greater than 90 and less than 180 degrees.
What is an angle more than 180 degrees and less than 360 degrees called?
An angle that is more than 180 degrees and less than 360 degrees is called a "reflex" angle.NoteAngles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle.Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles.An angle that is exactly 180 degrees is called a "straight line".Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
Can a regular polygon's interior angles measure 40 degrees?
No. To elaborate, the smallest regular polygon, an equilateral triangle, has 60 degree interior angles. The next larger one, a square, has 90 degree interior angles. In fact, for any regular polygon, the interior angles measure 180*(n-2)/n degrees, where n is the number of sides. No polygon has less than 3 sides. Thus, no regular polygon can have interior angles less than 60 degrees.
