While studying through the number system, i notice that positive side is from 0 to +ve infinity. The direction is left to right. However, this is opposite in case of angles. The sort of curved number system starts from 0 to 180 ( from right to left). Is their any good reason why unlike a number system, direction of measuring angles is right to left ?
PS: I actually first thought that, it's due to +x +y axis-plane coming on the right side. But then what about -x + y plane coming on the left side. The angles should go negative after 90. ie. -91, -92.... -180.
Logic probably is something different! What is it ?
