At 10, the hour hand and the minute hand form an angle of 60 degrees. 10, the minute hand refers to 12 and the hour hand refers to 10. There are two big squares between these two numbers, one is 30 degrees, and the other two are 60 degrees, so when 10, the hour hand and the minute hand form a right angle of 60 degrees.
It can also be explained in this way: on the clock face, a * * is surrounded by the number 12, and we can divide them into equal parts 12, in which if the watch core is centered, the rounded corner is 360 degrees.
So there is a big grid between every two numbers, and the angle between each big grid and the watch core is 360 degrees divided by 12 to get 30 degrees. Finally, look at what the hour hand and minute hand refer to when the hour is 10. There are several big squares between the two hands, that is, there are several 30 s.
When the hour is 1, the minute hand refers to 12 and the hour hand refers to 10, so there are two squares, so when the hour is 10, the hour hand and the minute hand are a right angle of 60 degrees.
How to learn to watch?
First: first of all, learn to look at the needle. The hour hand is the shortest hand on the dial. Every time the hour hand moves a number on the dial, it is an hour, and a circle is 12 hour.
Second: Second, learn to watch minutes. The longest pointer on the dial is the minute hand. The minute hand is different from the hour hand. It takes five minutes for a number to walk around the dial and sixty minutes to turn around. When the minute hand turns once, the hour hand will go by a number, which is one hour.
Third: the second hand is the thinnest hand on the dial. Every time the second hand moves a number on the dial, it is 5 seconds, and every turn is 60 seconds. Every time the second hand turns, it moves a number every minute, which is one minute.
Fourth: If you learn to look at the hour hand, minute hand and second hand, you can know the time on the dial by looking at the watch.
The above is the way to look at the watch.
