Major arc
The number of degrees in a circle is always 360.The number if degrees in a part of a circle is that same part of 360.In 74.2% of a circle, there are 74.2% of 360 degrees.
It would be call the ARC.
A circle has 360 degrees. Hence 20 degrees is 20/360 = 2/36 = 1/18 part of a circle.
It is 90 degrees of the circle's circumference which has a full turn of 360 degrees.
360
An 'arc' is part of the circumference of a circle.
A defined continuous section of the circumference is called an arc.
As in a unit circle, 30 degrees is Pi/3.
A circle has 360 degrees. Divide 360 by 18 and you will find that each equal part of the divided circle is 20 degrees.
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
They are quite similar but a angle isbasically part of the circle. if a had an angle of 90 degrees then it is aquarterof the circle. the circle it the whole thing and the angle is part of the thing
1 whole circle = 360 degrees2/360 = 1/180 of a circle
