True providing that they have the same diameters
2 circles can be congruent. The have to have the same radius.
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
congruent circles
Yes. Congruent circles by definition have the same size, and the radius sufficiently describes the size of a circle.
No. They can me different sizes. For a shape to be congruent, they need to me same size and same shape.
True providing that they have the same diameters
They are congruent or identical circles
All circles are similar, they all are the same shape, regardless of size. Only if they have equal diameters, would they be congruent.
They are not all the same length. If that was the case all circles would be the same size.
Yes, it is. Circles that are in the same plane and having the same center are called congruent circles.
Circles with the same radius are congruent circles.
2 circles can be congruent. The have to have the same radius.
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
