Answer:
Not congruent; not congruent; congruent; congruent; not congruent; not congruent.
Step-by-step explanation:
The base of △ABC, BC, is 2 units. The height of △ABC, extending from A to BC, is 3 units. This means that any triangle congruent to this will have a base of 2 and a height of 3.
△MNP has a base of 2; however, its height (from M to NP) is 4 units. Therefore they are not congruent.
△EFG has a base of 2 and a height of 4; it and △ABC are not congruent.
△STU has a base of 2 and a height of 3; it is congruent to △ABC.
△EFG has a base of 2 and a height of 4, just as △MNP; they are congruent.
Since △STU is congruent to △ABC, and we know that △EFG is not congruent to △ABC, we know that △EFG is not congruent to △STU.
Since △MNP is congruent to △EFG, and △EFG is not congruent to △STU, then △MNP is not congruent to △STU.
