You can draw in ai. Here are the specific steps.

Open ai, create a new canvas and draw an ellipse. Use the direct selection tool to taper both ends of the ellipse. Click the rotation tool, move the center point, set the angle to 60 degrees, and then click Copy. Copy Ctrl+D for many times to get the following pattern. Using the ellipse tool, press the shift key to draw a circle. Fill it with the right color as needed.

Summary: When designing a pattern, you should first choose a good pattern. You can choose a pattern to arrange regularly and paint it with different colors to form a pattern. You can also use different patterns to form different patterns and then paint them. We began to design patterns and color the prepared square paper.

There are all kinds of beautiful patterns in life, and plane and three-dimensional architectural art and geometric images can be seen everywhere. A large part of its design uses the translation, symmetry and rotation of mathematical graphics. Let students discover and collect these patterns by themselves and appreciate them, which can not only broaden their horizons, but also let them appreciate the beauty in life and mathematics.

Designing patterns can make students interested in mathematics and gradually find mathematics interesting. It is a masterpiece of human thinking, so students are interested in the practicality of mathematics and geometry. Students' feelings of learning mathematics will also be greatly encouraged.
