__Straight Line Curves__

What is a straight line curve?

A straight line curve is just like it sounds! You can create curves using straight lines if you draw the lines at the same angles. View the image above. If every straight line is drawn at the same angle, then "d" will be the same distance in between each line. In the case above, because there are four sides, there will be four curved lines.

How can it be used in a Zentangle?

In the Rick's Paradox pattern, straight lines are used to make curved lines. In the example to the left, the original shape is a triangle, which has three sides, so the result is three curved lines!

The curved lines seem to spiral into a center: this is called a logarithmic spiral. Each curved line that reaches from one corner of the original shape (in this case, a triangle) to the center of the spiral is the length of one side of the original triangle.
