GS - Geometry H.- Ch.1 - Points, lines, and planes

Equidisant Points edually distant from each other.
A Point It has no lenth, no width, and no thickness.
A Line Infinite set of points that extend in two directions. A line has lenth, but no width and no thickness.
A Plane An infinite set of points that creates a flat surface that without ending. A plane has lenth and width, but no thickness.
Space The set of all points.
Collinear Points on the same line.
Noncollinear Points not on the same line.
Coplanar Points on the same plane.
Noncoplanar Points not in the same plane.
Intersection Lines, segments, planes, etc... that cross each other at one point.
Segment Named by giving its endpoints.
Ray Named by giving its endpoint and another point on the line with one arrow.
Lenth The distance between two points.
Congruent Two objects that have the same size and shape.
Midpoint of a segment A point that divides a segment into two congruent segments.
Bisector of a segment A segment bisector is a line, segment, ray, or plane that intersects a segment at its midpoint.
Angle A figure formed by two rays with the same endpoint
Measure of an angle A protractor, or computing the absolute value of the difference of these numbers can be used to find the ...
Acute 0 < m
Obtuse 90 < m
Right m
Straight m
Congruent angles Two angles with equal measures.
Bisector of an angle The ray that divides an angle into two congruent angles.
Adjacent angles Coplanar angles with a common vertex nand a common side but no common interior points.
