Geometry Definitions

Akopọ

Before you can prove anything in geometry, you need to agree on what the basic objects are. What exactly is an angle? What makes two lines parallel, or perpendicular? These foundational definitions are the bedrock on which every geometric argument is built.

In this lesson you will learn precise definitions of the most fundamental geometric terms: angle, circle, perpendicular line, parallel line and line segment. Each definition is exact, so that everyone using it means precisely the same thing, which is what makes geometry rigorous.

Awọn Afojusun

  1. Know precise definitions of angle, circle, perpendicular line, parallel line and line segment.

Akọ̀wé Ẹ̀kọ́

Geometry is built on precise definitions. A vague idea of 'parallel' or 'circle' is not enough to reason carefully or to follow a proof. Learning the exact meaning of each fundamental term gives you a shared, reliable language for describing and analyzing shapes.
