TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #November 26-30
Unit of InstructionUnit 4: Right Triangles and Trigonometry
Standard(s) Taught

MAFS.912.G-SRT.2.4:  Prove theorems about triangles.  (Theorems include the Pythagorean Theorem proved using triangle similarity).

MAFS.912.G-SRT.3.8:  Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

Learning Targets and Learning Criteria
  • Students will apply theorems, postulates, or definitions to prove theorems about triangles, including proving The Pythagorean Theorem using triangle similarity.
  • Students will use Special Right Triangles (45-45-90 and 30-60-90) to solve for missing side lengths.
  • Students will solve right triangles by finding the measures of all sides of the triangle using Pythagorean Theorem.
  • Students will draw right triangles that describe real world problems and label the sides with their given measures.
Classroom Activities


  • Students will take notes on Pythagorean Theorem and its Converse in their ISN (p. 28)
  • We will do a nearpod lesson together on the Pythagorean Theorem
  • Students will do a Pythagorean Theorem Murder Mystery activity
  • I will give students a handout on simplifying radicals using the Birthday Cake Method and will go through some examples with them.


  • Students will learn about 45-45-90 Special Right Triangles and will fill in a guided notes page and do some examples.


  • Students will do the guided notes page on 30-60-90 Special Right Triangles and will do some examples.
  • Students will then do the Special Right Triangles Task Cards.


Assignments Due
  • Pythagorean Theorem Murder Mystery activity due at the end of class on November 26/27.
  • Special Right Triangles task cards due on November 29/30.
