Studied by 1 personline
a straight set of points that extends infinitely in both directions
half line
a subset of a line consisting of all the points on a given side of a point on the line
Line Seperation Postulate
Every point on the line divides the line into three distinct parts: a point and two half-lines.
Ray
the union of a half-line and its origin
opposite rays
two rays that have a common endpoint and form a straight line
segments
consists of two endpoints and have a finite amount of points
Plane Seperation Postulate
Every line in a plane divides the plane into three distinct parts: the line and two half-planes
half-plane
a subset of a plane consisting of all points on a given side of a line in the plane
edge of a half-plane
The line that separates the plane into two half-planes.
Opposite half-planes
two half planes within a plane separated by a common edge
angles
union of two distinct rays with a common endpoint
angle sides
the two rays forming an angle
vertex
The common endpoint of an angle (shared by two rays)
interior of an angle
everything inside the angle
exterior of an angle
everything outside the angle
