# Areas Reference Page

Now that we've studied all of the lessons on the areas of various polygons and circles, it will be helpful to have key information and area formulas on one page for easy reference. This page is dedicated to outlining everything we have learned about the properties of different quadrilaterals, circles, and their areas. If you forget how to apply formulas, or want to read about the areas of various figures in detail, you can go back and click on the lesson of your choice.

## Basic Properties

The following table displays the properties of triangles and various types of quadrilaterals.

The previous table can help us remember the important characteristics of different figures. Let's look at a table that we can use if we want to work on problems involving area.

## Area Formulas

The following table illustrates various shapes and their corresponding area formulas.
