High school math and geometry vocabulary

High school math courses introduce their own specialized vocabulary alongside general reading words. In geometry, students learn terms like congruent, perpendicular, and hypotenuse to describe shapes and relationships between lines and angles. Building strong general vocabulary skills, like recognizing connotation or forming a hypothesis, also helps students read math word problems and textbook explanations more accurately.
