How can I make a double arrow head in order to indicate bond angles? Is there a way to put an arrowhead on the other end of the curved arrow?
You have two options:
1. Draw the curved arrow you want, and then use any of the arrows to draw just an arrowhead. Then move the arrowhead into position at the opposite end of the curved arrow to make a double-headed arrow.
2. Use the Pen tool to draw the curve you want, and then use the Curve menu to place an arrow head at the beginning and end of the curve.
