Q1, W6: September 16-20 Geometry

TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #Six
Unit of InstructionUnit One: Definitions, Segment and Angle Pair Relationships
Standard(s) Taught

MAFS.912.G-CO.3.9: Prove theorems about lines and angles; use theorems about lines and angles to solve problems. (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.)

Learning Targets and Learning Criteria
  • apply theorems, postulates, (including angle addition) or definitions to prove theorems about lines and angles.
  • define complementary and supplementary angles.
  • recall special angles formed when a transversal crosses parallel lines and use their relationships to solve problems.
  • use algebra to find missing angle measures when parallel lines are cut by a transversal
Classroom Activities

Tuesday:

  • 5th and 8th period will catch up any missing work and do more practice on angle measure bingo activity

Wednesday:

  • Students will play “Dance, Dance, Transversal” to review the angle relationships formed when parallel lines are cut by transversals

Thursday/Friday:

  • Students will work on a Parallel Lines Cut by a Transversal Puzzle Activity (with a partner they will solve twelve problems–finding the value of x and the measure of angle y; when they finish all twelve, they will cut the twelve boxes apart and arrange them so that all answers correctly line up)
  •  
Assignments Due
  • Parallel Lines Cut by a Transversal Puzzle due by Wednesday, September 25.
