As you've probably realized, triangles appear everywhere--as parts of buildings, bridges, sculptures, road maps, and walkways. Knowing the properties of various kinds of triangles and the theorems that apply to these very common shapes can help you in and out of geometry class. Look at each of the images below and think about how an understanding of triangles might help someone use or create the object in the picture. Then click the image to compare your ideas to ours.
In this lesson, you'll revisit some of the key properties and theorems related to triangles and learn how they that can assist you in solving problems. While you've surely already looked at many triangle problems by now, the focus of this lesson will be the "real-life" problems that you encounter outside of your math class.
