Applications of Right Triangle Trig
Lesson 8 of 17
Objective: SWBAT use trigonometric ratios to solve real-world problems.
Big Idea: Students work independently to solve right triangle trig problems in context.
Print Lesson
As a warm-up to today’s lesson, I will ask my students to complete the clicker questions located on pages 2-5 of today’s Flipchart_ Application of Right Triangle Trig (p. 1-5). These are very basic multiple choice questions that assess if students can solve right triangle trig problems out of context before we move into problems with context.

I present my plan for implementing this section of the lesson in the following video:
Applications of Right Triangle Trig, Word Problems, Plan for Implementation
We will be using the problems in this resource as we work:
Flipchart_ Application of Right Triangle Trig (p. 6-16)
You might want to review the video reflection Right Triangle Trigonometry in a Pre-Calculus class if you have questions about how today's lesson fits into the curriculum at my school.
