- . Choose the option Geometry->Edit-> Intersection->Lines.
- . Select the upper circumference
- . Select the line resulting from the 33-degree rotation (see next figure)
The two lines selected
- . Press ESC to conclude the intersection of lines.
- . Press ESC to finish the intersection function.
- . Create a line (Geometry->Create->Straight line) between the existent point (55, 0) and the point generated by the intersection.
- . Choose the option Geometry->Edit-> Intersection->Lines in order to make another intersection between the lower circle and the line segment between point (40, 0) and point (55, 0) (see next figure)
Intersecting lines
- . Then continue selecting to make an intersection between the upper circle and the farthest segment of the line that was rotated 36 degrees (see next figure)
