Geometry Flashcards
Point
A location - has no size or shape
Line
Made up of points
A line has no width or thickness
Line Segment
Point of a line consisting of 2 endpoints
Ray
Extends forever in 1 direction
Plane
A flat surface made up of points
Collinear
Points that lie on the same line
Coplanar
Points that line on the same plane
Congruent Segments
Line segments that equal the same
Segment Bisector
A line, ray, line segment, or point that cuts a line segment in half at its midpoint
Perpendicular Bisector
A line that bisects another line segment at a right angle, through the intersection point
Angle
Formed by two rays a common endpoint
Vertex
The common endpoint of an angle
Adjacent Angles
Two angles that are next to each other and share a common side
Vertical Angles
Two angles across from each other at intersecting lines
Linear Pair
Two angles that are adjacent and supplementary, needs to form a straight line
