Follow the mentioned steps to find the angle.<\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Place the center of the Protractor at a fixed point O, which is the point where both the lines making the angle meet.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Make sure to coincide the reference line on the Protractor with an arm of the angle at point O. This is the initial line (zero degrees).<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Another arm of the angle will now indicate the degree of angle formed.

It is always less than the right angle. Therefore, the range of acute angle degrees ranges from 0\u00b0 to 90\u00b0. Also, dividing the right angle in any way gives us two or more acute angles.
