8.G Tutor Intake — Transformations, Pythagorean Theorem, and Volume

This short check helps your tutor see where to begin. Answer each question on your own, without help or a textbook. If you are not sure, give your best try — the goal is to find what to work on together, not to grade you. You may use a calculator. Leave answers in terms of pi where asked.

Similarity and Angle Relationships

A transversal crosses two lines. A pair of alternate interior angles
formed by the transversal measure $70\degree$ and $110\degree$ (they
are not equal). What can you conclude about the two lines?

The two lines are not parallel — alternate interior angles are equal only when the lines are parallel.

The two lines are parallel — alternate interior angles are always equal no matter what.

The two lines are parallel, because the angles add to $180\degree$ .

There is not enough information; angle measures tell you nothing about whether lines are parallel.
