Background Tutorials

• Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

    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.

• Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.

    What is an Ordered Pair?

    Ordered pairs are a fundamental part of graphing. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like. This tutorial will introduce you to ordered pairs!

• Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.

    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!
