I am confident that the first option with the parallel lines is not sufficient since it doesn't indicate the angles are alternate interior and obviously not all angles created by parallel lines are congruent. As for the second one, I would say it's ok. The biggest issue is if teachers use certain symbols and/or abbreviations, the Regents raters may not be familiar with them (since teachers aren't supposed to grade their own exams).

Subject: Geometry Proof Question

While discussing the new curriculum and planning, we have a new teacher who has some different ways of completing proofs. We are wondering if anyone has seen them or would allow credit for it on the regents.

For example, she writes: (= means congruent)

//-> = <'s
for "parallel lines cut but a transversal form two congruent alternate interior angles"

or

= P = (triangle symbol) =
for "Corresponding parts of congruent triangles are congruent"

A couple of us are uncomfortable with these type of "reasons" on a proof and are curious, do you know if they would be given full credit and what your thoughts are. Thank you for your time.
