The included angle determines the endpoint of the arc. Use the Start, End,
Angle method when you know both endpoints but cannot snap to a center
point.
Draw Arcs by Specifying Start, Center, Length
When you have a start point and a center point you can snap to and you
know the chord length, use the Start, Center, Length or the Center, Start,
Length option.
The length of the chord of the arc determines the included angle.
Draw Arcs by Specifying Start, End, Direction/Radius
When you have a start point and an endpoint, use the Start, End, Direction
or the Start, End, Radius option.
The illustration on the left shows an arc drawn by specifying a start point,
endpoint, and radius. You can specify the radius by entering a length or by
moving the pointing device clockwise or counterclockwise and clicking to
specify a distance.
