Grade Level8th
Week #7
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.

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
