Math Vocab Flashcards
Acute
An angle that has a measure more than 0 and less than 90 degrees
Adjacent angles
Two angles that share a common vertex and side , but have no common interior points
Angle
A set of points consisting of two different rays that have the same endpoint
Angle bisector
A ray that divides an angle into 2 angles that are congruent
Axiom
A rule that is accepted without proof
Between
When three points are collinear, one point is between the other 2
Collinear points
Points that lie on the same line
Complementary angles
Two angles who’s measures have a sum of 90
Congruent angles
2 angles that those the same measure
Congruent segments
Line segments that have the same length
Construction

Coordinate
A real number that corresponds to a point on a line
Coplanar points
Points that lie on the same line
Defined terms
Terms that can be described using known words , such as point or line
Distance
The absolute value of the difference of two coordinates on a line
Endpoints
Points that represent the ends of a line segment or ray
Exterior of an angle
The region that contains all the points outside of an angle
Interior of am angle

Line segment
Consists of 2 endpoints and all the points between them
Linear pair
To adjacent sent angles whose noncommon sides are opposite rays
Measure of an angle
