Reasoning: If you know one angle measure of a parallelogram, how do you find the other three angle measures? Explain.

Compare and Contrast: What is the difference between a quadrilateral and a parallelogram?

Error Analysis: Your classmate says that QV = 10. Explain why the statement may not be correct.

Review Lesson 6-1: Match the interior angle sums on the left with the with the polygons on the right. Not all angle sums will be used.

Review Lesson 4-6: What additional information do you need to prove the congruence statement below using the HL Theorem?

Review Lesson 6-3: Two consecutive angles in a parallelogram have measures x + 5 and 4x - 10. Find the measure of the smaller angle. Enter only a number.
