It also doesn't follow exactly at the equatorial line.

同学们又问了：我们可以在这个切面上做一个到赤道线的垂线吗？

Thee students asked:can we make a projection line to the Equator line on a plane?

如果有一条线和赤道线平行，而且经过尺的顶端，这条线和尺的夹角就等于纬度。

If there is a line passing the top of the ruler, and parallel to the equator, then the Angle between the line and the ruler is equal to the latitude here.
