Regulatory Symbol Rules

Point position x-regulator sign   y-regulator sign  Regulatory Symbol
In the first leg             +                     +        (+,+)
Second leg              –                     +        (-,+)
In the third leg              –                     –         (-,-)
In fourth leg             +                     –         (+,-)

(1) Regulatory sign rules = (0,0)

(2) What is the x-k regulator called? = abscissa

(3) What is the regulator of y ?=Grade

(4) Regulator or x coordinate of x axis = x, 0

(5) Regulator or coordinate of y axis = 0, y

(6) The formula for the distance from the point of origin = √ x² + y²

(7) Distance formula = √ (x1-x2) ² + (y1-y2) ²

(8) On the x-axis, y = 0.

(9) x = 0 on the y-axis.
