2b. A student claims that any two congruent triangles must have the same perimeter. Do you agree or disagree? Why?

i disagree

Step-by-step explanation: just because the triangles are congruent doesnt mean they are they same size so they can be bigger or smaller and have  different perimeter

Agree

Step-by-step explanation:

Congruent Triangles have 3 equal sides and 3 equal angles, though these can be 3 different numbers both triangles will have the same 3 numbers.

So congruent triangles are basically copies of each other. They will always have the same perimeter because they have the same side values as each other.

Say Triangle A has 3 sides with lengths 3,4 and 6. Triangle B has lengths 4,6 and 3. They both have the same angle measures.

As you can see, although the side lengths are rearranged they have the same values. So that means that all triangles congruent to one another will have the same perimeter.
