Quilting Patterns
In a common style of quilting, each square patch is constructed from a simple
"core square" design. In the Mathlet below, the large core square
at the top can be designed by first choosing a color from the palette and then
clicking one of the eight sections of the core square.
Below the core square appear three common ways to assemble the core squares
into a quilt patch. In each of the quilt patch designs, the original core square
appears in the upper right.
- Repeated: In the repeated pattern, the core square is simply
copied three times without being transformed.
- Reflected: In the reflected pattern, the core square is
first reflected over a vertical line, and the result is placed to the left
of the original. Then that square is reflected over a horizontal line, and
the result is placed below the previous result. Finally, that core square
is flipped over a vertical line and the result is placed in the lower-right
of the quilt patch.
- Rotated: In the rotated pattern, the core square is rotated
90 degrees counter-clockwise several times, each time the result being placed
around the quilt patch, starting in the upper-right and going around to the
lower-right.
Using the Mathlet below, create several different core square
designs, and investigate the different kinds of quilt patches you can create.
After you have explored a bit, try to answer the questions appearing below the
Mathlet.
Questions:
- Can you create a core square for which the repeated and reflected patterns
look the same?
- Can you create a core square for which the repeated and rotated patterns
look the same?
- Can you create a core square for which the reflected and rotated patterns
look the same?
- Can you create a core square for which all three patterns look the same?
