1. share 3 properties ex. The shape is the same, the color is the same, and the shading is the same but the number is different.
2. share only one common property ex. The shape is different, the color is different, the shading is different but the number is the same.
3. share no common properties ex. The shape is different, the color is different, the shading is the different, and the number is different.
