• #### What is a Theorem?

Theorems are a way for mathematicians to make a general mathematical statement. These statements can be used to help you solve all sorts of problems! See an introductions to theorems with this tutorial.

• #### How Do You Write the Converse, Inverse, and Contrapositive of a Conditional Statement and Determine Their Truth Values?

A conditional statement is an if-then statement. For every conditional statement you can write three related statements, the converse, the inverse, and the contrapositive. The video shows how these are related.

• #### How Do You Write a Biconditional Statement?

If you can write a true statement using "if and only if" , then you've got a biconditional. Learn more about biconditionals by watching the video.

• #### What is Inductive Reasoning?

You probably observe data and patterns to make predictions or conjectures on a regular basis. If so, you are using inductive reasoning. Check out the video to learn more!

• #### What is a Biconditional Statement?

When a conditional statement and its converse are both true, you can write them as one statement called a biconditional statement. Learn more about this special kind of statement by following along with this tutorial.

• #### How Do You Write an Indirect Proof?

This tutorial looks at using an indirect proof to show that an equilateral triangle cannot have a right angle.

• #### What is a Point?

A point is a fundamental building block of math. Without points, you couldn't make lines, planes, angles, or polygons. That also means that graphing would be impossible. Needless to say, learning about points is very important! That makes this tutorial a must see!

• #### What is a Plane?

You can't learn everything about math without seeing planes. Did you know that there are rules for naming a plane? This tutorial introduces you to planes and shows you how to name them. Take a look!

• #### What are Parallel Lines?

Lines that are parallel have a very special quality. Without this quality, these lines are not parallel. In this tutorial, take a look at parallel lines and see how they are different from any other kind of lines!

• #### What are Skew Lines?

Ever heard of skew lines? They're pretty cool! Take a look at this tutorial and you'll be introduced to skew lines.
