MGR4 (Map Grid Reference, 4) Four Grid Reference
If the reference points are not correct, the location of any coordinate will be incorrect.
draw two lines perpendicular to each other. theses line will act as reference line. starting from reference line plot the point to its position.
Since the angle of 331⁰ is in the fourth quadrant, then the measure of its reference angle in the first quadrant is 360⁰ - 331⁰ = 29⁰ .
The reference angle for 325 degrees is 35 degrees which is found by subtracting 325 from 360 since it is in the third quadrant.
