Q1,W8: October 1-5

TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #Eight
Unit of InstructionUnit 2 (A): Triangle Congruence and Proofs
Standard(s) Taught
  • MAFS.912.G-CO.1.5:  Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using graph paper.
  • MAFS.912.G-CO.2.7:  Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.
Learning Targets and Learning Criteria
  • Students will learn how to dilate a figure around a point that is not the origin.
  • Students will learn the Triangle Congruence Postulates and see how they are used to prove that two triangles are congruent.
  • Students will learn how to apply the Triangle Congruence Postulates to determine whether or not two triangles are congruent.
Classroom Activities

Monday/Tuesday:

  • We will look at Geometry Nation video on dilations and learn how to dilate a figure around a point that is not the origin.
  • We will practice some of these together.
  • Students will do a Mathspace on Transformations.

Wednesday:

  • Students will create a Triangle Congruence foldable for their ISN (page 13)

Thursday/Friday:

  • Students will do a Formative Assessment on Transformations to prepare for upcoming test
  • We will begin working on the Triangle Congruence Theorem packet (Let’s Practice Geometry)
Assignments Due
  • Mathspace on Translations, Reflections, and Rotations due by Monday, October 8.
  • Formative Assessment on Transformations due at the end of class Th/Fri. October 4/5.
