Answer:
1--- not congruent
2--not congruent
3---congruent
4---congruent
5---not congruent
6---not congruent
Step-by-step explanation:
This is true because the congruent figures are equal to each other, the not congruent shapes are not congruent because they don't equal each other.(the answers are right but I am quite bad at explaining things)
Two figures are congruent if and only if there exists one or more rigid motions which will map one figure onto the other.
