Angle - Wikipedia
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 angle (between 90 ...

Acute Angle definition - Math Open Reference
Acute angles are the smallest, being between (but not including) zero and 90° Note also that acute triangles are those where all the interior angles are acute.. A way to remember Sometimes we can confuse acute and obtuse angles.

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.
