Most of the Arc tools are identical to Circle/Ellipse tools. After the initial circle is created, the arc is cut from it by defining the start and end angles.You can display the Arc toolbar by right-clicking in any toolbar area and selecting Arc. 
Start and end angles can be changed with the Edit Tool (node editing). See Editing Circles, Ellipses, and Arcs.
