A triangle has three sides, three angles and three vertices. How many dependencies are there between two triangles to be congruent?

In the figure, Rectangle $ABCD≌$ Rectangle $PQRS$.

The congruency of rectangles depends upon

Circle A and circle D are congruent. If the diameter of circle A is 12 cm, what is the radius of circle D?

Choose the correct option:

In the above figures, length is not the only element of dependency of congruency in

The length of the side of the square EFGH is 4 units. Another square UVXY also has the same measure for its length namely, 4 units. Are the two squares congruent?

The given two rectangles ABCD and PQRS are congruent. This means all sides and angles exactly match each other. Accordingly, the side which is congruent to side PS =
