Answer:
not congruent;not congruent;congruent;congruent;not congruent;not congruent
Explanation:
In order to be congruent,the side lengths of both triangles must be equal.
The base of triangle ABC is 2 units.the base of triangle MNP is also 2 units.the hieght of triangle ABC is 3 units;but the base of triangle MNP is not 3 units,it is 4. The triangle are not congruent.
Similarly,both ABC and EFG have a base of 2 units. However,the height of ABC is 3 while the height of EFG is 4;the triangles are not congruent.
The base of ABC and STU are both 2 units,and the height of each is 3 untis the triangles are congruent.
The base of EFG is 2,as is the base of MNP ,both triangles also have a height of 4;the triangles are congruent.
The base of EFG is 2 units,as is the base of STU . however,the height of EFG is 4 while the height of STU is 3;the triangles are not congruent.
The base of STU is 2 units, as is the base of MNP .however,the height of STU is 3 while the height of MNP is 4;the triangles are not congruent.
