Yes, circles with equal parameters, specifically equal radii, are congruent. This means that if two circles have the same radius, they can be perfectly overlapped without any gaps or overlaps. Congruence in circles is determined solely by their radii, as all circles are similar in shape. Therefore, equal parameters imply congruence.
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.
Are congruent circles.
Congruent circles
All circles are similar, they all are the same shape, regardless of size. Only if they have equal diameters, would they be congruent.
If they're in the same circle or in circles of equal radii (radiuses), then yes.
yes
Yes
Only if they belong to congruent circles.
Arcs, in the same circle or in congruent circles, that have equal measures.
Yes. Congruent circles by definition have the same size, and the radius sufficiently describes the size of a circle.

Congruent circles
Are congruent circles.
True providing that they have the same diameters

Yes.
Circles that have congruent radii. Congruent=coinciding at all points when superimposed (http://dictionary.reference.com/browse/congruent)
