Question

Where does the "right" come from in a angle?

Answer 1

if its a 90degree angle, it is considered "right." i think its because its the middle of being a line and a ray, and all the trig stuff works with them, and stuff like that. its not like right and left, its like right and wrong. thats my opinion anyways.

make it a good day

Answer 2

It is probably related to "upright",

since if one side is horizontal, the other is vertical or upright.
