A mathematical tabloid picture about the corner: math diary

Today, we learned lines and angles. I learned about right angles, acute angles, obtuse angles, right angles and rounded corners. When I got home, my mother asked me, "Do you know what angles the hour hand and the minute hand form in the watch?" I thought about it, picked up the small alarm clock and said, "One, two, eleven and ten o'clock are acute angles, three or nine o'clock are right angles, four, five, seven and eight o'clock are obtuse angles, six o'clock is right angles and twelve o'clock is rounded corners." My mother gave me a thumbs-up and said, "Well, that's nice!" I'm so happy! I thought to myself: Mathematics is everywhere in my life, so I must study hard!

Mathematical tabloid pictures about angles: angles and right angles.

There are many children in the corner, including the right angle. One day, the right angle said, "I am the most useful and omnipotent, like squares, rectangles, cubes and cuboids, and I am the most important." My brother and I can't compare. " After listening to the instruction, Jiao said, "You are wrong! You are important, but so is your brother. Just like a triangle, you can live without it, but you can't live without your brother. In people's life, there are many places where you are, but in nature, your brothers and sisters are more and more ubiquitous than you. "

Today, I was reviewing math, and my mother came up to me and asked me, "How was your review?" I replied, "No problem." Mom then asked, "Can I test you?" "Of course." I am eager to answer. Mom immediately said, "Can you draw an angle of 135 with a triangle?" I thought, I'll draw the angle with a protractor, or let me draw it with a triangle. I really haven't drawn it yet. Mom saw that I didn't make any noise, so she said, "Think about it!" Suddenly my mind flashed and I thought that one angle of the isosceles triangle was 45. Find a right angle to spell it 135. I started painting at once. My mother saw it and said, "Hmm! That's right. Can you draw an angle of 75, 105, 120, 150? " I said confidently, "No problem." Then I drew these angles with the angles of 90, 60, 45 and 30 of two triangles respectively. When my mother saw that I drew all the pictures correctly, she praised me and said, "It seems that you have learned this part of knowledge very well and know how to use it flexibly. Today, I passed! " I jumped up happily and said, "Oh! You can go out to play! " I am happy to think, fortunately, I remember to use all the corners of the triangle, otherwise today will be over, and I will have to think more when I encounter problems in the future.

Today, I learned new knowledge. In the first, second and third grades, I only knew acute angle, right angle and obtuse angle. But starting today, I will learn more angles.

In math class, I made two new friends, one is a boxer and the other is a rounded corner. These two new friends will accompany me to study and live from now on. These two angles, like the previous angles, have a common feature, that is, two straight edges emanate from one point. These six angles have their own characteristics different from other angles. Let's start with the acute angle, 1 ~ 89 degrees. Except for right angles, right angles are 90 degrees. Then the obtuse angle is an angle greater than 90 degrees and less than 180 degrees. The flat angle is 180 degrees.

A fillet is an angle of 360 degrees.

Although boxers and rounded corners are new roles, they still exist in life. You see, after the minute hand of the clock turns for 30 minutes, it forms a right angle, the minute hand turns once, forming a rounded corner, and the swivel chair turns once, forming a rounded corner. In fact, straight corners and rounded corners are still very common.

Everyone knows that the earth moves around the sun. When the earth revolves around the sun, it also rotates.

When the sun just rises in the morning, it will form an angle of 0 degrees with the ground. The sun will form an acute angle with the ground in the morning. At noon, the sun is directly above and will be at right angles to the ground. The sun will form an obtuse angle with the ground in the afternoon. When the sun goes down, the sun will form a right angle with the ground, and the sun will rise from the horizon the next morning, when the sun will form a rounded corner with the ground.

Before, I only knew the simplest three angles (acute angle, right angle and obtuse angle). Now that I have grown up, I know two new angles: straight angle and rounded angle, and I also know their meanings.

Also, I know that the light emitted by the sun can be regarded as rays, the road can be regarded as straight lines, and the two rails on the railway can be regarded as parallel lines. These are all knowledge related to lines and angles in our lives.

About the corner of the mathematical tabloid picture content 6: the kingdom of the corner

One day, I had a strange dream that I came to the kingdom of horns. When I came, I saw many angles, including right angles, acute angles and obtuse angles. Look at them living happily together.

Right angles are unique there. They can form many squares and rectangles, but don't underestimate those acute and obtuse angles. Compared with the straight back of right angle, acute angle and obtuse angle are much easier. As their backs change, many different angles are formed. Our life is inseparable from these strange corners, such as books, desks, blackboards and so on.

Students, let's remember our good friends "Angle and right angle"!
