Did you know?
Did you know you can draw a curve using straight lines? Cardioid is the Greek word for heart. This geometric shape was first drawn by Giovanni de Castillon in 1741. It is created by drawing evenly spaced lines around a circle.
With the ruler, connect the points: Connect 1 to 2, 2 to 4, 3 to 6, etc. Do you see the pattern? For each line, the beginning point is one space in front of the one before and the ending point is two spaces in front of the one before. Continue until you beginning point is at 60 (the ending point goes around the circle twice).
STEP IT UP
Try a different pattern. What happens when you move the end point three spaces instead of two?
