Method of making cone with paper
Prepare a piece of square colored paper and fold it along the dotted line as shown in the figure.
At this time, you will get a small square and draw a fan with a compass, as shown in the figure. If you don't have a compass, you can use a ruler to measure the side length of a small square, and then take the vertex of the lower left corner as the starting point, point out several points of the same length, and gently connect them with a pen to form an approximate arc.
Cut along the line with scissors.
Unfold the paper and it will be a circle.
As shown in the figure, use scissors to cut along the dotted line, cut the quarter of the circle, and apply glue stick in the shaded area.
According to the figure, pull the red edge on the right side and the blue edge on the left side and squeeze them tightly.
The cone is ready!
