7.G.A.2 Tutor Intake -- Triangle Conditions and Uniqueness

This short check helps your tutor see where to start. Work on your own,
without a calculator. If you're unsure, give your best try — the goal is
to find what to work on together, not to grade you.

Concepts

Two students each construct a triangle with sides 5 cm, 7 cm, and
9 cm. Student A's triangle looks like a mirror image of Student
B's triangle when placed side by side. What can you conclude?

The two triangles are congruent — a mirror image (reflection) still counts as the same triangle.

The two triangles are different, since one is flipped and the other is not.

Only one of the two students followed the SSS conditions correctly.

The triangles cannot be compared without also knowing their angles.
