Then two points with a radius of 1/2 are taken on two mutually perpendicular diameters,
Finally, make four small circles with these four points as the center and 1/2 as the radius.
It became a figure in the book.
Draw a circle first, and then draw a diameter through the center of the circle.
Then draw two 60-degree angles with the center as the vertex and the radius as one side.
And they extend to four point where that diameter intersects the circle.
Finally, connect the six points on the circle to form the figure in the book.
Draw a circle first, and then draw a diameter through the center of the circle.
Take two points with a radius of 1/2 on this diameter,
Finally, make two small semicircles with these two points as the center and 1/2 as the radius.
It became a figure in the book.
The key to this drawing problem is to determine the position of the center of the circle first.
