Objective

Students will be assessed on Line-sanity units with a summative exam or problem set that covers alternate interior angles, vertical angles, perp lines and other key line relationships.

Big Idea

Challenge students with this unit test or problem set covering perp and parallel lines, perp bisectors and many more line related topics

Standards

HSG-CO.C.9

Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment's endpoints.

HSG-CO.D.12

Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.). Copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line.

HSG-GPE.B.5

Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

MP1

Make sense of problems and persevere in solving them.

MP3

Construct viable arguments and critique the reasoning of others.

MP5

Use appropriate tools strategically.

MP7

Look for and make use of structure.

Review of Student Questions

15 minutes

Before taking their unit assessment, you can review the practice unit test which students worked on last class. This is a great opportunity to allow students to ask last minute questions and also ensure that all students have the correct materials (i.e. compass!) for this test.
