Angles and Arcs in Clocks

In this picture angle EJF equals 135.15 and is congruent to its arc EF which equals 135.19. This is because a central angle inscribed in a circle is congruent to its arc.

[Note: The numbers are slightly off though because the angle is not exactly in the center of the clock. This makes the numbers not perfectly equal but if the angle was in the center the angle and the arc would be congruent.]
