Card Set Information
remy geometry vocab
Chapter 1 cards for Mr. Remy's geometry classes at Duxbury High.
Words that are not explained by using more basic words. The basic undefined terms of geometry are point, line, and plane.
A location. (point is an undefined term)
A collection of point, with no thickness, that extends forever in two opposite directions. (line is an undefined term)
A flat surface, with no thickness, that extends forever in all directions (plane is an undefined term)
Points that lie on the same line.
Points and lines in the same plane.
A, B, and C are coplanar
The set of all points that are common to two or more geometric figures.
A boundless three-dimensional set of all points.
Part of a line consisting of two endpoints and all points between them.
Segments that have the same length.
A geometric figure created using a straightedge and a compass.
Distance (between two points)
The length of the segment between two points.
A number that cannot be expressed as the quotient of two integers.
A point that divides a segment into two congruent segments.
B is the midpoint of segment AC.
A segment, line, or plane that intersects a segment at its midpoint.
Part of a line consisting of one endpoint and all the points of the line on one side of the endpoint.
Two collinear rays with the same endpoint.
An object formed by two rays with the same endpoint.
The point of intersection of two rays.
An angle with a measure equal to 90 degrees.
An angle with a measure less than 90 degrees.
An angle with a measure greater than 90 degrees and less than 180 degrees.
An angle with degree measure equal to 180.
A ray that divides an angle into two congruent coplanar angles.
Two coplanar angles with a common side, a common vertex, and no common interior points.
A pair of adjacent angles whose non-shared rays form a line.
Two nonadjacent angles formed by two intersecting lines.
Two angles whose measures have a sum of 180 degrees.
Two angles whose measures have a sum of 90 degrees.
Two lines that intersect to form right angles.
A closed plane figure with at least three sides. The sides intersect only at their endpoints, and no adjacent sides are collinear.
Vertex of a Polygon
The vertex of each angle of a polygon.
A polygon for which there is a line containing a side of the polygon that also contains a point in the interior of the polygon.
A polygon for which there is
line that contains both a side of the polygon and a point in the interior of the polygon.
A polygon with n sides.
A polygon whose sides are all congruent.
A polygon whose angles are all congruent.
A polygon that is both equiangular and equilateral.
The sum of the lengths of the sides of a polygon.
The distance around a circle.
The number of square units needed to cover a surface.
