Autodesk Inventor - 2D Sketch Constraints

What is the definition of a "constraint" in inventor?

• Restrictions and associations that are applied to 2D geometry (shapes, points, lines) to make them line up or connect in a certain way

• The limits and restrictions a designer must consider at the beginning of a project

• Devices that keep a person from moving

• Specifications for the size of a design, 2D or 3D

Which constraint symbol matches coincident: occurring together in space or time. For example, the ends of the lines were coincident - they were on top of each other.

Which constraint will make lines parallel? In math terms, it makes them have the same slope.
