Similar, in most instances. All their interior angles add to 360 (without exception), however, the measure of the diameter, perimeter (etc) could be different.
Circles that have congruent radii. Congruent=coinciding at all points when superimposed (http://dictionary.reference.com/browse/congruent)
Circles with the same radius are congruent circles.
Congruent arcs are circle segments that have the same angle measure and are in the same or congruent circles.
Congruent Arcs
Congruent circles, maybe...
No. There are big ones, medium ones, and little bitty ones.But all circles are similar.
Circles are congruent when they have the same radius and they are similar when their radii are different in lengths.
Congruent circles
No. They can me different sizes. For a shape to be congruent, they need to me same size and same shape.
Are congruent circles.
A sphere is.
Yes.
Congruent circles
Circles that have congruent radii. Congruent=coinciding at all points when superimposed (http://dictionary.reference.com/browse/congruent)
All circles are similar, they all are the same shape, regardless of size. Only if they have equal diameters, would they be congruent.
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.
Yes, it is. Circles that are in the same plane and having the same center are called congruent circles.
