Angle - Wikipedia
Individual angles. An angle equal to 0° is called a zero angle. Angles smaller than a right angle (less than 90°) are called acute angles ("acute" meaning "sharp").; An angle equal to 1 / 4 turn (90° or π / 2 radians) is called a right angle.Two lines that form a right angle are said to be normal, orthogonal, or perpendicular.; Angles larger than a right angle and smaller than a straight ...

Miter saw tables and acute angles - install Crown
Using a prosite protractor makes finding the acute angle, such as a 45 ° X 45 ° X 90 ° inside crown on a coffered ceiling, easier. Then you can read the scale for the miter cut which is the angle bisected, or dived in half.

Special right triangle - Wikipedia
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.
