Q2, W7: January 5 – 8 Pre-Algebra

TeacherKristin Andreason
Subject AreaPre-Algebra
Grade Level8
Week #January 5-8
Unit of InstructionFocus 7: Angle Pair Relationships
Standard(s) Taught

MAFS.8.G.1.5: Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.  For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.

Learning Targets and Learning Criteria
  • informally prove the angle-sum theorem, the properties of angles when parallel lines are cut by a transversal and the angle-angle criterion for similar triangles. 
  • prove that the sum of any triangle’s interior angles will have the same measure as a straight angle. 
  • make conjectures regarding the relationships and measurements of the angles created when two parallel lines are cut by a transversal. 
  • apply proven relationships to establish minimal properties to justify similarity. 
  • present informal arguments as to whether or not triangles are similar based on Angle-Angle criterion.
