Minute is the basic unit of angle, which is converted into 60 decimal system, once equal to 60 minutes. The conversion formulas are1= 60 ′,1′ = 60 ″, 1 = 3600 ″. The earth is 360 degrees, and it's 24 hours a day. If you divide it into several minutes, you will get 60 minutes.

Besides, the second is also the basic unit of angle. The conversion formula between the two is that one time equals 60 points, and one point equals 60 seconds. But the minutes here have nothing to do with time, and the angle is a mathematical concept. It can describe the size of the angle, that is, the amount that must be rotated when either of the two intersecting lines overlaps the other intersecting line.

The importance of angle:

1, the angle can be expressed in many ways.

The most commonly used method is degree representation. In this representation, a complete circle is divided into 360 angles, so an angle is a part of the circle, and the arc length of the circle is 360 degrees.

2. Angle has many applications in mathematics.

In geometry, it is used to measure the size of a shape. In other words, if the appearance of a polygon is the size of an angle, then it is a polygon. Similarly, angle can also be used to measure the included angle between two straight lines, which is the basic operation of building geometric figures.

3. Angle is also widely used in physics.

Physicists use angles to measure the inclination between planets and other celestial bodies in the solar system. In electronics, angle is also used to measure the included angle of tiny charged particles in the medium, so as to measure the route they are guided when they gather or extend, that is, the direction they are guided when they are influenced by the external environment.
