Finding the missing length of a side of a right triangle? If you have the other two side lengths, you can use the Pythagorean theorem to solve! Check out this tutorial and see how to use this really helpful theorem to find that missing side measurement!
Think your triangle is a right triangle? Want to be sure? If you have the length of each side, apply the Pythagorean theorem to the triangle. If you get a true statement when you simplify, then you do indeed have a right triangle! If you get a false statement, then you can be sure that your triangle is not a right triangle. Check out this tutorial and learn how use the Pythagorean theorem to see if a triangle is a right triangle!
The converse of the Pythagorean Theorem is like the the Pythagorean Theorem in reverse. You can use it both forward and backward! Not all theorems work this way, but the Pythagorean Theorem does! This tutorial will show you how to use both the Pythagorean Theorem and its converse.
The Pythagorean theorem is a very popular theorem that shows a special relationship between the sides of a right triangle. In this tutorial, you'll get introduced to the Pythagorean theorem and see how it's used to solve for a missing length on a right triangle!
The sine ratio is a handy ratio when you're dealing with right triangles! In this tutorial, you'll learn what the sine ratio is and how to use it to find angle measurements in a right triangle.
There are several different ratios you can make from the sides of a right triangle. One of them is the tangent ratio. Watch this tutorial to add the tangent ratio to your right triangle tool box!
Want to find a missing side or angle measurement of a triangle? The Law of Sines can help! Follow along to learn about this handy proportion.
To find the geometric mean of two numbers, just find the product of those numbers and take the square root! Follow along with this tutorial to learn the process step-by-step.
The geometric mean can help you find a missing term in a geometric sequence. Before you find the geometric mean, you should understand what it is. This tutorial defines geometric mean.
When you're following directions, you not only need to know how far you're traveling but in what direction. Vectors are just like that! They have both a length and a direction! Follow along with this tutorial to learn about vectors and their parts. You can even see how to name a vector!
