Here are the commands you can give to your turtle on the turtle tab.

	clean - Clears the screen of all drawings and send the turtle to the middle.
	forward - Moves the turtle forward the number of pixels entered.
	back - Moves the turtle backward the number of pixels listed.
	left – Changes the turtle’s direction to the turtle’s left by the angle specified.
	right – Changes the turtle’s direction to the turtle’s right by the angle specified.
	arc – Draws part of a circle. The angle is the part of the circle the turtle draws. The radius determines the width (size) of the circle.

Here is a sample of some angles. They can be used for the right and left commands and to draw arcs.
