"Understanding of Fan Shape" Circle PPT Courseware

Summary: Characteristics of Circles

1. It is a flat curve figure;

2. There is a center of the circle (a point o in the center);

3. There are radius (r) and diameter (d):

Within the same circle (or equal circles), there are countless radii, all of which have the same length; there are countless diameters, all of which have the same length, and the diameter is equal to twice the radius (d=2r).

The wheel is made into a circle based on the geometric properties of circles: the radii of the same circle are equal. When the wheels roll on flat ground, the wheel axles are always on a plane at the same height, so the rider will not feel bumpy and comfortable.
