The activity/homework asks students to look for repeated reasoning to use coordinate geometry to find the 4th point in a parallelogram (MP8). Although the questions are scaffolded for students questions #1-7 and the proof #8 require students to work through and persevere through both challenging problems, just as they were required to in the proofs earlier in class (MP1).

Ok, I just assumed that the material you have here went in order of how you taught it.

Hi Amanda,

We cover congruent triangles prior to quads so this is why we can use ASA. HOpe that helps!

Probably getting tired of me asking questions, and I know there is no way I will know before I teach this lesson, but I am having trouble with the 1st proof in the notes. How do you prove the sides congruent if you have not covered angle/side/angle?
