When the clock face is tick, the angle formed by the hour and minute hands is an acute angle, drawin

The smaller angles formed by the hour and minute hands at one o'clock and eleven o'clock are acute angles.

The smaller angles formed by the hour and minute hands at four and eight o'clock are obtuse.

There are 60 360 degrees on the clock, with 6 degrees each.

At 2 o'clock, there are 10 divisions between the hour and minute hands, and the number of sharp angles clamped is (60) degrees.

At 3:30, there is a grid between the hour and minute hands, and the number of sharp angles clamped is (75) degrees.

Use the number 360.

Because it is easily divisible. In addition to 1 and itself, 360 also has 22 true factors, including numbers from 2 to 10 other than 7, so many special angles are integers.

In practice, the angles of integers are accurate enough. Sometimes more accurate measurements, such as astronomy, are needed.

Or the latitude and longitude of the earth, in addition to decimals to express degrees, you can also subdivide degrees into minutes and seconds: 1 degree is 60 minutes (60), 1 is divided into 60 seconds (60). For example = 40°11 15 .

To be more accurate, seconds are expressed as decimal numbers, and no units are added. Acute angles are those that are greater than 0° and less than 90°.

At 10 o'clock, the hour hand points to 10, the minute hand points to 12, according to the clock face is divided into 12 large grids, each large grid is 30 degrees to obtain the degree of the acute angle between the hour hand and the minute hand on the clock watch = 2 30 ° = 60 °, is the acute angle;

At 5 o'clock, the hour hand points to 5, the minute hand points to 12, according to the clock face is divided into 12 large grids, each large grid is 30 degrees to obtain the degree of the acute angle between the hour hand and the minute hand on the clock = 5 30 ° = 150 °, which is an obtuse angle; Answer: At 10 o'clock, the angle between the hour hand and the minute hand is an acute angle; At 5 o'clock, the angle between the hour and minute hands is obtuse

What time is the hour and minute hands on the clock face at right angles.

1, 2, 10, 11 o'clock on the clock face.

The hour and minute hands are at acute angles.

3,9 o'clock on the clock face, the hour and minute hands at right angles.

4, 5, 7, 8 o'clock on the clock face.

The hour and minute hands are obtuse.

At 6 o'clock on the clock face, the hour and minute hands are at flat angles.

The needle-shaped parts on the surface of the timer, such as the timer, indicate the hour, and the needle-shaped part on the surface of the timer, such as a clock, is divided into a long hand and a short hand, and the short hand indicates the "hour", which is called the "hour hand".

Chinese name hour hand.

Foreign name hour hand

Pinyin shí zhēn

Zhuyin Paraphrase: The hand on the clock that moves in hours.

At 6 o'clock on the clock face, the angle formed by the hour and minute hands is a flat angle, and the flat angle is 180°

1, 2, 10, 11 o'clock on the clock face.

The hour and minute hands are at acute angles.

3,9 o'clock on the clock face, the hour and minute hands at right angles.

4, 5, 7, 8 o'clock on the clock face.

The hour and minute hands are obtuse.

At 6 o'clock on the clock face, the hour and minute hands are at flat angles.

At 5 o'clock, the angle of the hour hand and the minute hand on the clock face is: 30° 5=150°, which is an obtuse angle;

So the answer is:

Because it is 48 times, the reason: because the hour hand rotates 30° in 1 hour, it rotates in 1 minute, and the minute hand rotates 6° per minute

After x minutes, the hour hand and the minute hand are at a straight elimination angle, then there is an equation for the state.

x(6° How many times will the 90° bridge mask be different in 24 hours?) There are n times, then.

This results in n=88

In these 88 times, the angles of the hour hand and the minute hand are 90°, 180°, 270°, and 360° respectively, of which 180° and 360° are not satisfactory, so there are a total of 44 right angles in 12 hours, and there are 9:00 and 3:00 in 12 hours, there are two, and there are 24 hours, there are 4 times, so 44 + 4 = 48 Answer: 48

Let's talk about things, this is the clock face, and the hour and minute hands have an angle. I found that the feet gradually became larger, indicating that the size of the horns is related to time. But time has no size. Time is only a long time.

Another question, if defined in terms of angles, what is an angle? What is now referred to as an angle is a geometric definition. Geometry is defined as a geometric object consisting of two beaming lines with a common endpoint.

Its common endpoint is called the vertex of the branch angle, and in general, the angle refers to the same plane. The size of the angle has two sides, that is, the degree of ray opening, and the larger the opening, the larger the angle. Therefore, it can also be said that if you notice that your feet are gradually getting bigger, it means that the degree to which you feel that the size of the hour and minute hands is related to the degree of openness.

I hope you can give me my opinion, thank you.

When the hour and minute hands on the clock face are at a flat angle, that is, the angle is 180°, it is exactly 6 o'clock;

So the answer is: 6

On the tabletop, a flat angle is formed between the hour and minute hands, which should be 60 inters.

Summary. At 3 o'clock, the hour hand points to 3 and the minute hand points to 12, so it is 90 degrees, at right angles.

At 3 o'clock, the smallest angle of the hour and minute hands on the clock face is ().

Right angle. At 3 o'clock, the hour hand points to 3 and the minute hand points to 12, so it is 90 degrees, at right angles.
