The included angle of an arc is the angle formed between the center, start point, and endpoint of the arc.

Define the term point of tangency.

The point of tangency is the point shared by two tangent objects.

Name the two axes found on an ellipse.

The two axes on an ellipse are the major axis (the longer axis) and the minor axis (the shorter axis).

When you use the Center, Radius option of the CIRCLE command, what are the options for specifying the radius?

Type a value and press [Enter] or use point entry or drawing aids.
