    It’s not pedantry, you just don’t know elementary level geometry.

    https://en.m.wikipedia.org/wiki/Right_angle

    Right angles must be comprised of two straight lines, and by also by similar definition a curved line can’t be perpendicular to fucking anything.

    That angle can be 90 degrees at the point of intersection because of how angles in this case are measured but it is not a right angle or perpendicular. This why the definition of right angle is more complex than “a 90 degree angle.”

      pedantic/pə-dăn′tĭk/

      adjective

      1. Characterized by a narrow, often ostentatious concern for academic knowledge and formal rules.

        “a pedantic attention to details.”

      You are very much correct in the fact that angles by definition are only present between straight lines. A secant line that is in the same plane as the circle and is crossing the centre of the circle is called it’s normal and a normal is by definition perpendicular. The meme was fun
