Trigonometry Workshop for High School

This approach to visualizing trigonometry is based on how the great mathematicians learned to measure chords in circles and use these measurements to accurately map the celestial objects in the sky. It is my
experience (in formal classrooms and tutoring) in teaching Grades 10, 11 and 12 that students have an easier time understanding and applying the trigonometry concepts when given the opportunity to see and explore the origins of this mathematics. This is how I begin with the students: “Tell me all that you know about triangles.”
