Congruent circles
A detripage
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.
If they're in the same circle or in circles of equal radii (radiuses), then yes.
Yes. All radii of the same circle have the same length.

congruent circles
a cylinder has two faces that are circles
Their circumferences are in direct proportion to their radii. Their areas are in direct proportion to the square of their radii.
Congruent circles, maybe...
