In commerce, liquid oxygen is classified as an industrial gas and is widely used for industrial and medical purposes. Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.
Lesson Summary. An acute angle is any angle smaller than 90 degrees. A right angle is an angle that measures 90 degrees. It doesn't matter how much smaller the angle is than 90 degrees; as long as it's smaller, it's acute. To unlock this lesson you must be a Study.com Member.
TopIf measure of any angle is less than 90 degree then angle is known as Acute Angle. In other words acute angle has measure less than 90 degree. So we can say that acute angle lies between 0 and 90 degree. Meaning of word acute is sharp. Here we will discuss how many acute angles can a Scalene Triangle have. First we will understand the concept of scalene triangle. In Geometry, scalene triangle looks like an Acute Triangle; it is so because each angle of an acute angle is less than 90 degree. It always follows properties of a scalene triangle.
