Welcome Geometry Students!

Hey Geometry Class!

"All About Geometry" is a blog site to help you succeed in this course. I will post lesson reviews and key concepts that you can use while completing homework assignments and studying for quizzes/exams.

You can also post questions on here - anything within the blog rules is fair game. You can ask for further explanation on a concept or even for help on a homework problem. I promise to address all relevant and appropriate questions either in class, on this site, or both.

Notice that newest posts are at the top of the page. In some cases you may want to look at older posts to master concepts that newer posts build upon.

Take a look around and enjoy!

Incenter


The angle bisectors of the interior angles of a triangle are concurrent. Their point of intersection is called the Incenter. The incenter is the center of a circle that inscribes the triangle (click on the picture above for a larger view).

What do we know about the radius of the circle that inscribes the triangle?
