If those Points are from DIVIDE-ing two concentric Arcs in the configuration that would result from Offsetting one to get the other [whether you actually made them that way or not], then there's a way to do this without the Points at all. You can put those Lines in place directly from the original Arcs, without DIVIDE-ing them first.
Go and get DivideMeasurePlus.lsp, >>here<<. Load that.
Draw a vertical Line of the distance between the Arcs, anywhere. You can draw it between Arc ends, and ROTATE it to be vertical. [It needs to be vertical, for the options described below, so that the alignment direction tangent to an Arc at a given location along the Arc will place each copy of the Line perpendicular to the Arc.]
Call up the DIV+ command. Choose the User-Selection option [one of the major enhancements compared to ordinary DIVIDE], and select that Line. When it asks for a "Base point in relation to selection: ", pick the bottom end of the Line.
Accept the offered default Aligned option for the rotation. Give it your number of segments [160 in your example]. Accept the offered Standard default for placement in relation to the segment-division locations, and the offered 0 default for inset from the ends [another option regular DIVIDE doesn't offer], and the offered Yes default for placement at the ends [yet another thing regular DIVIDE won't do].
When it asks you to "Select object to divide: ", pick the outer Arc, anywhere.
You can get the same result from it in some other ways: you can pick the top end of the Line as the base, and pick the inner Arc to divide; or you can draw the Line horizontally, and use the Relative-angle to the path rotation option [another choice not available in ordinary DIVIDE], and give it 90 degrees and pick the outer Arc, or 270 degrees and pick the inner one.
