Chapter 1: Geometry Terms

Vocabulary flashcards defining fundamental geometry terms: plane, ray, parallel, angle, and intersect.

Plane

A flat, two-dimensional surface that extends infinitely in all directions.

Ray

A part of a line that begins at a fixed starting point and extends infinitely in one direction.

Parallel

Lines, planes, or surfaces that remain equidistant from each other at every point and never meet or intersect.

Angle

A figure formed by two rays that share a common endpoint, known as the vertex.

Intersect

To meet, touch, or cross at a common point, line, or set of points.
