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.
Two arcs are congruent if they have the same measure in degrees or radians, and they belong to the same circle or to congruent circles. This means that their lengths are equal, and they subtend the same central angle. Additionally, congruent arcs can be thought of as having identical properties, even if they are located in different congruent circles.
yes
Yes
Yes. Congruent circles by definition have the same size, and the radius sufficiently describes the size of a circle.
Only if they belong to congruent circles.
Arcs, in the same circle or in congruent circles, that have equal measures.
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.
