Preparation: Download the geometric sketchpad software.

Draw two intersecting circles. Select the [Circle Tool] on the left sidebar, and then draw two circles in the working area so that they intersect. The intersection points are A and B, as shown in the figure.

Construct an arc on circle c1. Select points B, A and circle c1 in sequence, and execute the [Construction] - [Arc on Circle] command, thus completing the arc construction operation on the circle.

Construct an arc on circle c2. Select points A, B and circle c2 in sequence, and execute the [Construction] - [Arc on Circle] command, thus completing the arc construction operation on the circle.

Construct the interior of the bow. Select the two constructed arcs and execute the [Construction] - [Arc Interior] - [Arc Interior] command, so that the interior composed of the two arcs can be filled.

Adjust the color inside the bow to be consistent. Select the inside of the two bows respectively and execute the [Display] - [Color] command, so that their colors can be adjusted to the same.

Note: If there is a crack between them at this time, connect the intersection points of the two circles and adjust the color of the resulting line segment to the same color as the inside of the arc. If the color of the line is darker than the inner color at this time, right-click the inner part of the bow and select [Properties], and adjust the transparency to 100%.
