Right Triangle Trigonometry
Trigonometry is the study of right triangles, in particular the relationship between their sides and angles. In this topic, you explored the three primary trigonometric functions: sine, cosine, and tangent. You learned how to find side lengths as well as angle measures. A strong foundation in the primary trigonometric functions is the basis for further exploration of the remaining three core trigonometric functions: secant, cosecant, and cotangent.
