the measure of an angle is 8 degrees less than 3 times the
Acute angles are narrow (less than 90 degrees), obtuse angles are wide (greater than 90 degrees), and right angles are exactly 90 degrees (two lines perpendicular to each other).
When we measure angles using the protractor, we should remember the following steps.If we add all three angles in any triangle we get 180 degrees.But the measure of arc AC is the same as the measure of the central angle, AOC.
If the angle is drawn to scale you can use a protractor to measure the angle.Our wiki is made for math and science Master advanced concepts through explanations, examples, and problems from the community.
