Can you find the length of a missing side of a right triangle? You most likely can: if you are given two side lengths you can use the Pythagorean Theorem to find the third one. But, what if you …

Learn how to use trig functions to find an unknown side length in a right triangle.

Not only are right triangles cool in their own right (pun intended), they are the basis of very important ideas in analytic geometry (the distance between two points in space) and …

If what I'm saying is unfamiliar, I encourage you to review the right triangle trigonometry, and if the things I did about segment congruence and congruent triangles and similar triangles …

If you aren't, I encourage you to review all of the trigonometry on Khan Academy, especially the basic right triangle trigonometry. But this tells us that sine is opposite over hypotenuse, cosine …

Given one side length and an acute angle in a right triangle, find another side using trigonometry.

A guide to right triangle trigonometry on the digital SAT

You can draw a right triangle with the exact measurements and then just use a ruler to figure out the missing side (s). But people don't normally give you triangles with the exact measurements …

This unit introduces you to the foundational geometry and trigonometry skills you'll need on the SAT Math test, starting with more basic examples. We suggest leveling up each skill with …

Explore the world of trigonometry by mastering right triangles and their applications, understanding and graphing trig functions, solving problems involving non-right triangles, and …
