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!
Rays are a very useful part of math. Two rays can create an angle. Multiple angles can create a polygon. Add another dimension, and you get three-dimensional solids! This tutorial introduces you to rays and shows you how to name them.
The coordinate plane has two axes: the horizontal and vertical axes. These two axes intersect one another at a point called the origin. Learn about the ordered pair that indicates the origin and its location in the coordinate plane by watching this tutorial!
You can't graph a function or plot ordered pairs without a coordinate plane! Learn about the coordinate plane by watching this tutorial.
Understanding how angles are made in the coordinate plane is a big step towards understanding trigonometry. This tutorial shows you how an angle can be made in the coordinate plane!
