its Less than 90 degree
Two anlges are complementary if the sum of their degree is 90. So given any angle A less than 90, if angle B is complemenatry its has degree measurement 90-A.
An acute angle
They are obtuse angles.
An angle greater than 0 but less than 90 degrees is an acute angle
its Less than 90 degree
This is an Obtuse angle, greater than 90 but less than 180 degrees
less than 90 degrees is called an acute anlge
An angle that has a degree of less than 90 is called an acute angle.
Two anlges are complementary if the sum of their degree is 90. So given any angle A less than 90, if angle B is complemenatry its has degree measurement 90-A.
An acute angle
less than 90 degrees
They are obtuse angles.
A 5 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
More than 90 AND less than 180.
an infinite fraction of a degree less than 90 or 90 minus 1/infinity
An angle greater than 0 but less than 90 degrees is an acute angle
