Curve
A line that
is not straight is a curve. There are two types of curves.
Closed Curve
If a curve begins and ends at the same point, it is known as a closed
curve.
If a closed
curve does not cross itself, it is a simple closed curve. The first four
figures are examples of simple closed curves.
Open Curve
If a curve does not end at the starting point, it is known as an open
curve.
