NET
A two-demensional diagram that you can fold to form a three-dimensional figure.
ISOMETRIC DRAWING
A corner view of a three-dimensional figure.
POINT
A location (has no size).
LINE
A straight path that extends in two opposite directions without end and has no thickness. It contains infinitely many points.
PLANE
A flat surface that extends without end and has no thickness. It contains infinitely many points.
COLLINEAR POINTS
Points that lie on the same line.
COPLANAR
Points or lines that lie in the same plane.
SEGMENT
A part of a line that consists of two endpoints and all points between them.
RAY
A part of a line that consists of one endpoint and all the points of the line on one side of the endpoint.
OPPOSITE RAYS
Two rays that share the same endpoint and form a line.
POSTULATE
An accepted statement of fact.
INTERSECTION
A set of points two or more geometric figures have in common.
COORDINATE
A real number that corresponds to a point.
DISTANCE
An absolute value of the difference of the coordinates of the endpoints of a segment.
CONGRUENT SEGMENTS
Two segments that have the same length.
MIDPOINT
A point that divides the segment into two congruent segments.
SEGMENT BISECTOR
A point, a line, a ray, or a segment that intersects a segment at its midpoint (divides a segment into two congruent segments.
ANGLE
A geometric figure formed by two rays with the same endpoint.
VERTEX OF AN ANGLE
An endpoint of the rays that formed an angle
CONGRUENT ANGLES
Angles with the same measure.
ADJACENT ANGLES
Two coplanar angles with a common side, a common vertex, and no common interior points.
VERTICAL ANGLES
Two angels whose sides are opposite rays.
COMPLEMENTARY ANGLES
Two angles whose measures have a sum of 90.
SUPLEMENTARY ANGLES
Two angles whose measure have a sum of 180.
LINEAR PAIR
A pair of adjacent angles whose noncommon sides are opposite rays.
ANGLE BISECTOR
A ray that divides an angle into two congruent angles.
MIDPOINT
A midpoint of a segment i a point that divides the segment into two congruent segments
POLYGON
A closed plane figure formed by three or more segments.
CONVEX POLYGON
A polygon that has no diagonals with points outside the polygon
CONCAVE POLYGON
A poligon that has at least one diagonal with points outside the polygon
PERIMETER OF A POLYGON
The sum of the lengths of all sides
AREA
The space inside the figure
