A circle divides a plane into three parts.
Yes, there can be congruent arcs on a circle. Arcs which subtend the same angle at the center are considered as congruent.

Half of the circle is an arc
The angle of rotation for a point on a circle to draw an equilateral triangle is 120 degrees, as the triangle's three equal angles divide the circle into three equal 120° arcs.
No
An arc is a portion of a circle. The default method for drawing arcs is to specify three points-the start point, a second point, and the endpoint. You can draw an arc using several different methods.
Diameter
Because they are parts of the circumference of a circle
In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent.
