There are several formulas for the rhombus that have to do with its: … WebAn angle equal to 0° or not turned is called a zero angle. An angle smaller than a right angle (less than 90°) is called an acute angle ("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.
