• Points and Lines

  • • 

    What are the Endpoints of a Line Segment?

    A math term can really tell you a lot about the thing it's describing. Take the term 'endpoints'. The endpoints of a line segment are just the 'points' located at the 'ends' of the line segment! That's an informative name! Watch this tutorial to learn about endpoints of a line segment.

• Planes and Angles

  • • 

    What is an Angle?

    Angles are a fundamental building block for creating all sorts of shapes! In this tutorial, learn about how an angle is formed, how to name an angle, and how an angle is measured. Take a look!

• Triangle Definitions

  • • 

    What are Acute, Obtuse, and Right Triangles?

    Did you know that there are different kinds of triangles? Knowing how to identify these triangles is an important part of solving many problems involving these triangles. Check out this tutorial and learn about some of the different kinds of triangles!

• The Distance Formula

  • • 

    What Is the Distance Formula?

    If you need to find the distance between to points on the coordinate, you'll probably use the distance formula to get your answer. This tutorial introduces you to the distance formula and even shows you how to find it!

• Finding Missing Angles

  • • 

    What is the Sine Ratio?

    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.

• Commutative Associative and Identity Properties

  • • 

    What are the Commutative Properties of Addition and Multiplication?

    The commutative property is a fundamental building block of math, but it only works for addition and multiplication. This tutorial defines the commutative property and provides examples of how to use it.

• Ordered Pairs and The Coordinate Plane

  • • 

    What is the Coordinate Plane?

    You can't graph a function or plot ordered pairs without a coordinate plane! Learn about the coordinate plane by watching this tutorial.

• FOIL and Multiplying Binomials

  • • 

    How Do You Multiply Binomials Using FOIL?

    Looking for practice using the FOIL method? This tutorial delivers! It takes you step-by-step through the FOIL method as you multiply together to binomials.

• Square Roots

  • • 

    What Happens When You Square a Square Root?

    Remember that addition and subtraction are opposite operations and multiplication and division are opposite operations? Turns out, squaring and taking the square root are opposite operations too! See why in this tutorial!
