Subject AreaGeometry Honors
Grade Level8
Week #January 20-24
Unit of InstructionUnit 4: Right Triangles and Trigonometry
Standard(s) Taught

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
  • use Special Right Triangles (30°-60°-90° and 45°-45°-90°) to solve for missing side lengths.
  • 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.
  • draw right triangles that describe real world problems and label the sides and angles with their given measures.
  • solve application problems involving right triangles, including angle of elevation and depression, navigation, and surveying.
Classroom Activities


  • Students will do a Special Right Triangles relay race in groups of 3-4 students.
  • Then we will start the Special Right Triangles Swipe Out game


  • We will finish the Swipe Out game


  • I will introduce Trigonometric ratios
  • Students will create a foldable on Trig Ratios
  • We will watch the video “Gettin’ Triggy Wit It”
  • We will do a Kahoot on Trig Ratios
