Geometry

High school geometry courses take abstract concepts that students have previously learned and expand them in complexity and real-world application. So this branch of high school mathematics becomes not only more challenging, as the geometry operations become more involved, but also more exciting, as students see how geometry concepts apply to creating a wide variety of useful and necessary things in the real world. But learning geometric proofs about circles and triangles, understanding geometric rigid motions, and relating geometric points to the solution of equations all require a thorough grounding in high school geometry vocabulary.

The math vocabulary lists are based on the Common Core High School Math Standards. VocabularySpellingCity has selected the high school math words that apply to the key math concepts and written level-appropriate high school math definitions combined with meaningful example sentences. High school students can use these materials for reinforcement to build understanding or assessment. Teachers can import the lists into their account and then edit or extend the lists for their own purposes.

The geometry word lists are correlated to the Common Core State Standards, giving high school students a good grasp of the meanings and use of geometry terminology. Students can play fun geometry word games and hear high school geometry terminology spoken in contextual sentences. Whether students later go on to use geometry to create blueprints for buildings, to estimate volumes in a chef's kitchen, to gauge concrete pouring on a construction site, or to streamline vehicles for the greatest energy efficiency, a thorough grasp of high school geometry vocabulary can help shape a bright future!
