Do You Recognize
This Traditional Block?
This is interesting. These 2 very different traditional blocks have the same outline pattern. How they are colored is what makes them different.
What if you were to try other color combinations, could you come up with other blocks that use the same outline pattern?
The blocks so far all have vertical symmetry, horizontal symmetry, and rotational symmetry. They are also all colored blue and white.
This block has vertical symmetry and horizontal symmetry, but it is not the same when it is turned 90 degrees, so it lacks rotational symmetry.
You can think of this as being the block or you can think of the simpler version as being the block; it doesn't matter. What matters is you now have a design you can use.
