How was it determined that a circle is 360 degrees and all angles of a triangle equal 180 degrees?
idk but that's what the teachers say so i believe them..
I NEED HELP
lots of reasons can be found by googling the question
here is just one of them
The fact that the angles in a triangle add up to 180 is a function of the 360 definition.
Had the circle been defined as 500 degrees, then the angles of a triangle would add up to 250
