MoI has a mechanism called "Construction Lines" which is used for that type of stuff. You can trigger it in any drawing command by pressing and holding the mouse button down while dragging away from a target point. A construction line will appear which can be used for getting various extension and intersection points.

There is more detailed information on it here:
