Q3, W2: January 10-14 Geometry

TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #January 10-14
Unit of InstructionUnit 4: Right Triangles and Trigonometry
Standard(s) Taught

MAFS.912.G-SRT.2.4:  Prove theorems about triangles. (Theorems include: Triangle Proportionality Theorem or Side Splitter Theorem – a line parallel to one side of a triangle divides the other two proportionally; the Pythagorean Theorem proved using triangle similarity.)

Learning Targets and Learning Criteria
  • apply theorems, postulates, or definitions to prove theorems about triangles, including proving The Pythagorean Theorem using triangle similarity.
  • use angle measures to estimate side lengths and vice versa.
  • solve right triangles by finding the measures of all sides and angles in the triangles using Pythagorean Theorem and/or trigonometric ratios and their inverses.
Classroom Activities


  • I will give students notes on the Pythagorean Theorem and Its Converse and we will go over 
  • We will watch a video on Proving the Pythagorean Theorem
  • I will break down the proof of the Pythagorean Theorem and help them see how it is based on similar triangles
  • Students will do IXL’s Q.1 and Q.3 on the Pythagorean Theorem and the Pythagorean Inequality Theorem


  • Students will work on their Dilations Project which we already set up


  • Students will finish their Dilations Project
  • If they finish, they can finish working on IXL’s
Assignments Due
  • IXL’s Q.1 and Q.3
  • Dilations Project
