Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Solve It! Use the information given in the diagram. Which triangles are congruent? How do you know?

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.

  • 1080
  • 6840
  • 4140
  • 7200
  • decagon
  • 16-gon
  • 25-gon
  • 40-gon

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

G.SRT.5

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.

Enter only a number.

Enter only a number.

Use Your Vocabulary: Use the diagram above to match consecutive angles.

  • ∠A
  • ∠C
  • ∠D
  • ∠F
  • ∠E
  • ∠D
