Math Fact

Did you know that geometry is one of the oldest mathematical sciences? It was formally created by Euclid in the 3rd century BC. That is over 2300 years ago. If you are my student, about 15 years old, that means it is about 153 times older than you.

Famous Math Quote

Finding Sector Area of a Circle

In this video, I explain the definition of a sector and how to find the sector area of a circle. I work 2 example problems, one for finding the sector of a circle and the other to find the radius of a circle with a given sector area.

This website is dedicated to mostly geometry because I'm a geometry teacher. Included on this website will be videos of geometry throughout the year and I'm going to try and add a few interactive aspects where you can practice your math skills. Keep in mind this is a work in progress. I'm adding to this website as time goes by and it will take me many years to get this just right.
