Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
The idea is that three lines coming out from the center point of a circle (three radii) form three angles -- imagine, for an easy example, the Mercedes-Benz logo. Then the question is: if two of the angles each measure 130 degrees, what does the third angle measure? Well, the first two together measure 260 degrees. So, how many degrees in a circle overall are left, once 260 are taken out? There are 360 degrees in a circle, so the answer is 100.
360 degrees in a full circle 270 degrees in three quarters of a circle 180 degrees in a half circle 90 degrees in a quarter circle
there are 360 degrees in a circle, therefore a quarter is 90 degrees
135 degrees.
270 degrees
It was never confirmed. The degree was created as a unit equal to one three hundred sixtieth of the way around a circle
three eighths
216 degrees.
