Standards Addressed:
MGSE.9-12.G.CO.12 Make formal geometric constructions with a compass and straightedge. Copying a segment, copying an angle; bisecting a segment, bisecting an angle, constructing perpendicular lines including constructing a perpendicular bisector of a line segment and constructing a line parallel to a given line through a point not on a line.

MGSE.9.G.CO.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 equidistance from the segment’s endpoints.

Learning Targets /Success Criteria:
--I can solve for a missing angle using the angle addition postulate.
--I can identify and solve for a specified angle using the angle bisector theorem.


Introduction/Connection (Activator): Quizizz on vocabulary, angle addition theorem, angle bisector theorem, angle pairs

Direct Instruction/Guided Practice:
--review most missed problems from Quizizz
--practice on Triangle Inequalities (attached below).


Independent Practice/Collaboration/Differentiation:
--Students will complete Quizizz to review vocabulary, angle bisectors, angle addition postulate, special angle pairs
--Students will complete Unit #2, Quiz #1 on above
--Graphic organizers and foldables. Provide one-one-one help to students needing extra guidance provide enrichment problems for those students that understand the material quickly.
--Provide all accommodations as outlined in IEPs and 504s.

Summarizer/CFU: quick round robin review of vocabulary and/or steps for specific constructions.

Assignment: Students will finish DeltaMath lesson: Triangle Inequalities
