Green Bridge Learning Resource For Geometry Vocabulary

Overview

Geometry has its own precise vocabulary, and using it correctly is the difference between a clear argument and a confused one. The words for angles and triangles are not just labels: each carries an exact meaning that tells you something specific about a shape.

In this lesson you will learn precise definitions of the main angle types (acute, obtuse, right and reflex) and triangle types (equilateral, isosceles and scalene), along with related geometrical terms. Knowing exactly what each word means lets you describe, classify and reason about figures with confidence.
