Final answer:
In Onshape, a tangent arc must have its center at a certain distance from the circle and be drawn across the circle.
Step-by-step explanation:
In Onshape, a tangent arc requires the following:
- The center of the arc must be the radius distance away from the circle.
- No need to construct a perpendicular bisector.
- The tangent arc doesn't have to be created at the end of some other sketch.
- You must draw the arc across the circle.
So, the correct answer is A. Its center must be the radius distance away from that circle.
