What the word congruent and circle have in common is that circles have a congruent radii. All of the radii in a single circle is congruent to each other.
Yes
Are congruent circles.
Congruent circles
The sum of two radii of a circle is the same as the diameter of the circle.
Yes, all of the radii in a single circle are congruent.

Congruent circles
The sum of two radii of a circle is the same as the diameter of the circle.
A part of a circle enclosed by two radii is called a sector.
Yes. Congruent circles by definition have the same size, and the radius sufficiently describes the size of a circle.
If they're in the same circle or in circles of equal radii (radiuses), then yes.
I always called it an arc. It is simply a section of the circle. The ends are determined by the two radii you referenced. Each of the radii start at the center of the circle and end at their intersection with the circle. The portion of the circle that lies between the ends of the two radii is an arc.
You need only know the radius of each circle to determine that they are congruent. If the radii are identical, the circles are identical. This can also be determined by comparing the diameters (twice the radii), or the circumferences, or the areas of the circles. In all cases, if the parameters are identical, the circles are identical.
