Vocab 1
A specific Location.
Point
A 2-dimensional flat surface that extends indefinitely in all directions
Plane
Lines that intersect to form right angles
Perpendicular Lines
A ray that divides an angle into two congruent angles
Angle Bisector
Angles that have the same vertex and that share a common side
Adjacent Angles
Made up of points and has no thickness or width.
Line
Points and/or lines that lie on the same plane
Coplanar
A line or line segment that divides a line segment into two equal parts
Segment Bisector
An angle with a measure between 0 and 90 degrees.
Acute Angle
Opposite angles formed by the intersection of two lines. They are congruent.
Vertical Angles
Part of a line containing two endpoints and all of the points between them.
Line Segment
Coplanar lines that do not intersect
Parallel Lines
The point on a segment exactly halfway between the endpoints.
Midpoint
An angle whose measure is 90 degrees
Right Angle
Complementary
Three or more points that lie on the same line
Collinear
Two or more planes that do not intersect
Parallel Planes
The intersection of two rays at a common endpoint
Angle
An angle whose measure is between 90 and 180 degrees
Obtuse Angle
Two angles whose measures have a sum of 180 degrees
Supplementary Angles
A fixed part of a line that extends indefinitely in one direction.
Ray
Lines that do not intersect and are not coplanar
Skew Lines
The point at which sides of an angle meet
Vertex
Straight angle
Two angles that are adjacent and supplementary
Linear Pair
