Amongst polygonal shapes, only an acute triangle can have all its angles less than 90 degrees. Any other polygon must have one or more right or obtuse angles.
An equilateral triangle, which has 3 angles of 60o.
2, obtuse and reflex angles are larger than right angles A straight angle is larger.
A right angle is not 125
A Triangle which do not have a right angle.
supplementaryA:Two angles whose sum measures a right angle are complementary angles.

There are typically 3 angles, obtuse, acute, and right. obtuse- an angle that measures over 90° acute- an angle that measures less than 90° right- an angle that measures exactly 90°
