You can also measure angles by doing the following:
- To measure an angle from the x axis, drag the tool.
- To measure a custom angle, drag to create the first line of the angle. Then double-click or press Alt (Windows) or Option (Mac OS) while you click the start or end point of the measure line and drag to create the second line of the angle
By measuring an angle as in point 2, you will also be able to see in the Info palette, the length of the first line (D1) and of the second line (D2) which you traced with your Measure tool.
