An angle is measurement use to tell the distance between two lines that are concurrent at a point.
An arc is the length of a curve drawn with a unchanging distance (radius length) around a point..
Minor arc
There are three possibilities for the arc that lies between the sides of an angle (at the centre of the circle):semi-circleminor arcmajor arcWith any two points of the circumference of a circle they will make an angle at the centre of the circle.If the angle is 180o, then the two points lie on either end of a diameter and both arcs are the same length and are a semi-circle.Otherwise, the minor arc is the shorter of the two arcs, the major one is the longer one:The minor arc is the side of the angle that is smaller, ie the angle is acute (< 90o), a right angle (= 90o) or obtuse (> 90o & < 180o).The major arc is the side of the angle that is bigger, ie the angle is reflex (> 180o).
There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
Central angle
In a circle what is the difference between a central angle and an arc?Read more: In_a_circle_what_is_the_difference_between_a_central_angle_and_an_arc
the world may never know :D
They are normally the same. However, the measure of the arc could refer to the angle subtended at the centre of the radius of curvature.
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
there is not much difference
minor arc of cord is half of major arc of same cord
There is no difference in meaning between the two. It is usually spelled in lowercase, though (arc tan, or arctan).
Minor arc
minor arc
The arc formed where a central angle intersects the circle is called a "major arc" or "minor arc," depending on the size of the angle. The minor arc is the shorter path between the two points where the angle intersects the circle, while the major arc is the longer path. The measure of the arc in degrees is equal to the measure of the central angle that subtends it.
