An infinitely small segment of the arc can be.
Geometrically there isn't a problem. If you draw a line from that point to the center of the arc, it will make it clearer.

I guess if we define it as a calculus problem, I can see the point..

I didn’t mean to pun but there it is and I’m leaving it. Any way, there is no infinitely small section that’s perpendicular. Only the tangent at a single (infinitely small) point along a smooth curve, as we approach from either direction. Maybe that’s still called perpendicular.
