Common Core Standards
Define trigonometric ratios and solve problems involving right triangles
6. Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.
Everything you need for a full lesson or two to develop trigonometry from the tangent ratio to sine and cosine.
Presentations, worksheets, activities and solutions, covering all aspects of the Common Core Standards.
