Points Lines and Planes
Points that are on the same line
Collinear
PM + MQ = PQ
Between
Angles are measured using this
degree
Two nonadjacent angles that are formed by two intersecting lines. They intersect at only one point
Vertical Angles
A ray that divides an angle into two congruent angles
Angle Bisector
Points in the same plane
Coplanar
Used to find the distance between two points
Distance Formula
The common endpoint of two rays
Vertex
Two angles that together form a straight line
Linear Pair
Another way to describe a group of points
locus
Points are labeled with this
A capital letter
The point halfway between two other points
Midpoint
Angle greater than 90 degrees
Obtuse
Two angles whose sum is 90
Complementary Angles
When segments have the same measure then they are this
Congruent
Terms that are described with an example
A line, ray, or segment that intersects a segment at its midpoint
Segment Bisector
Angle equal to 90 degrees
Right
Two angles whose sum is 180
Supplementary angles
Angles that share one side
Adjacent Angles
A plane is named using this
Three non-collinear points
If B is the midpoint of AC, then AB = BC
Midpoint Theorem
Angle less than 90 degrees
Acute
Two lines that intersect to form a right angle
Perpendicular Lines
