...(360 degrees = 1 revolution.) 1 degree = 1° = Ую of a right angle. The degree is usually divided **into 60 equal parts called minutes ('), and each minute into 60 equal parts called seconds** ("); while the second is subdivided decimally. But for many purposes it is more convenient to divide... | |
