AutoCAD Inventor :: Use API To Add Coincident Constraint For Multiple Entities

I have created multiple sketch entities like line, arc, circle etc. using the Inventor API's. Now I want to add the coincident constraint between start point of line, start point of arc and center point of circle.

I have added coincident constraint through UI(Please see attached snap). The same I want to add using Inventor API's. which API I should use to add the coincident constraint for such multiple entities.
