## High School Geometry Worksheets

When people ask me my thoughts of geometry I always say, "It's the most useful math in the world!" If you use this type of math on a daily basis, as a grown-up, you must have a very accomplished career. Geometry under the core curriculum is a nice mix of of relevant real-world applications with a sprinkle of algebra and elementary trigonometry. Don't forget Geometry Math Posters make great visuals for your classroom.
