What Your Child Will Learn
- 1
Angle Vocabulary and Classification
Identify and classify angles by their measure: acute, right, obtuse, and straight.
Objective: Students will identify angles by type (acute, right, obtuse, straight) and estimate angle measures.45 minutes - 2
Complementary and Supplementary Angles
Understand and calculate complementary (sum to 90) and supplementary (sum to 180) angle pairs.
Objective: Students will identify complementary and supplementary angle pairs and find missing angle measures.45 minutes - 3
Vertical and Adjacent Angles
Identify vertical angles (equal) and adjacent angles, and use these relationships to find missing measures.
Objective: Students will identify vertical and adjacent angles and use their properties to find missing angle measures.45 minutes - 4
Triangle Angle Sum
Discover and apply the Triangle Angle Sum theorem: interior angles of a triangle sum to 180 degrees.
Objective: Students will discover that triangle angles sum to 180 degrees and use this to find missing angles.45 minutes - 5
Triangle Inequality
Determine whether three side lengths can form a valid triangle using the Triangle Inequality theorem.
Objective: Students will apply the Triangle Inequality theorem to determine if three lengths can form a triangle.45 minutes - 6
Exterior Angles of Triangles
Understand exterior angles and the Exterior Angle Theorem: an exterior angle equals the sum of the two non-adjacent interior angles.
Objective: Students will identify exterior angles and use the Exterior Angle Theorem to find missing angle measures.45 minutes - 7
Parallel Lines and Transversals
Identify angle relationships formed when a transversal crosses parallel lines.
Objective: Students will identify corresponding, alternate interior, alternate exterior, and co-interior angles formed by parallel lines and a transversal.45 minutes - 8
Angle Relationships Review
Review and consolidate all GE-7 angle relationship and triangle property skills.
Objective: Students will demonstrate mastery of angle relationships and triangle properties through mixed practice.45 minutes
