Q1, W4: September 21-25 Geometry

TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #September 21-25
Unit of InstructionUnit One: Definitions, Segment and Angle Pair Relationships
Standard(s) Taught

MAFS.912.G-CO.1.1:  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.

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
  • identify the undefined notions used in geometry (point, line, plane, distance) and describe their characteristics
  • identify angles, perpendicular lines, parallel lines, rays, and line segments.
  • define angles, perpendicular lines, parallel lines, rays, and line segments precisely using the undefined terms and “if-then” (conditional) and “if-and-only-if” (bi-conditional) statements.
  • identify and use the properties of congruence and equality (reflexive, symmetric, transitive) in proofs.
  • interpret geometric diagrams and identifying what can and cannot be assumed.
  • 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.
