Description

Want a completely interactive digital math lesson for high school geometry that will teach your learners all they need to know about trigonometry? In this lesson, learners will be able to apply trigonometric ratios to find angles and lengths in right-angled triangles in 2-dimensional figures.

Activities in this lesson include:

  • identifying the adjacent, opposite, and hypotenuse of a right triangle
  • identifying how sides are labeled
  • define trigonometric ratios and solve problems involving right triangles
  • apply trigonometry to general triangles
  • learn the exact values of sin θ and cos θ for θ = 0°, 30°, 45°, 60°, and 90°
  • learn the exact value of tan θ for θ = 0°, 30°, 45°, 60°

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.
Explain and use the relationship between the sine and cosine of complementary angles.
Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
Derive the formula 𝐴 = 1/2 𝘢𝘣 sin(𝐶) for the area of a triangle by drawing an auxiliary line from a vertex perpendicular to the opposite side.
Prove the Laws of Sines and Cosines and use them to solve problems.
