4) Arcs and Curves

Arcs and Curves

Arc command is found in the 'Turtle' palette.

Arc command is used to draw part of a circle (arc) or curves. Angle and radius are the two input values to be given in the arc command. The radius determines how big the circle has to be. The angle represents the the angle of the arc i.e., part of the circle to be drawn .

Here are few examples of the angle and the arc (is marked with the dotted lines) that will be formed:

The direction of the turtle makes a greater impact. For example see the below example. Though the angle and radius are same in both the set, since the directions of the turtle are different, the outputs are also different.
