Geo_Section 1-1 (Wk 1 VP)

A location with no size

An infinite number of points on a straight path that extends in two opposite directions with no end and has no thickness

An infinite number of points and lines on a flat surface that extends without end and has no thickness

Part of a line that consists of two points, called endpoints and all points between them

Part of a line that consists of one endpoint and all the points of the line on one side of the the endpoint

Formed by 2 rays with the same endpoint. Each ray is a side of the angle and the common endpoint is the vertex of the angle

A statement (also known as an axiom) that is assumed to be true without proof; it is used to support propositions and ultimately theorems

Points on the same line

Points or lines on the same plane

Two figures that have the same measurements and shape

The middle point of a line segment

The middle angle inside a larger angle

Undefined terms of geometry - They are the basic ideas you use to formally define or prove other geometry words and theorems. While they can be described by their characteristics, these descriptions are not Undefined terms of geometry - They are the basic ideas you use to formally define or prove other geometry words and theorems. While they can be described by their characteristics, these descriptions are not considered formal/precise definitions.

Says that every point on a line can be paired with a unique real number called the coordinate of the point. This allows a segment to be measured.

Says the measurement of an angle between two rays can be assigned a unique real number between 0 and 180 degrees. This allows the use of a protractor to measure angles
