How to use a compass to draw an ellipse Pictures or videos are best!

Tools needed: paper, grid ruler, pen, circle gauge, the steps are as follows:

1, prepare a piece of paper, draw a rectangle, circle four small rectangles, mark the points A, B, C, D and the center point O.

2, connect AD.

3, connect AC, BC and BD in turn, as follows.

4. Draw the centers at AC, AD, BC and BD with A and B as centers respectively.

5. Mark the four center points as 1, 2, 3 and 4.

6. Connect 1D.

7. Connect 2C, 3D and 4C in that order.

8. Connect points 1 and 2 with a circular gauge using E, the point where 1D and 2C are connected, as the center of the circle.

9. Again, using the point F where 3D and 4C are connected as the center of the circle, connect points 3 and 4 with a circular gauge.

10. Again using D as the center of the circle, connect points 1 and 3 with a circular gauge.

11, and then C as the center of the circle, using a circular ruler to connect 2 and 4 points, the ellipse is completed.
