Standards Addressed:
MGSE.9-12.G.CO.1 Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.


Learning Targets /Success Criteria:
I can apply the angle addition postulate to solve for missing angles in a triangle or diagram.
I can solve problems involving angle bisectors by finding the measures of angles using algebraic equations.


Introduction/Connection: (Activator): TBA.


Direct Instruction/Guided Practice:
--Introduce Angle Addition Postulate and Angle Bisector Theorem with foldable (attached below).
--Guide students in completing selected problems on angle bisector worksheet (attached below).


Resources: DeltaMath or IXL.
