voc. chapter 1 Flashcards
shows a corner view of a three dimensional figure.
isometric drawing
another way to represent a three dimensional figure.
orthographic drawing
indicates a location and has no size
point
represented by a straight path that extends in two opposite directions without end and has no thickness. contains infinitely many points.
line
represented by a flat surface that extends without end and has no thickness. contains infinitely nay lines.
plane
the set of all point sin three dimensions
space
is an accepted statement of fact
postulate or axiom
the set of points the figures have in common
intersection
the real number that corresponds to a point
coordinate
the distance between point A and point B is the ______ _______ of the difference of their coordinates.
absolute value
if the segments have the same length the segments are?
congruent segments
the _____ of a segment is the point that divides the segment into two congruent segments.
midpoint
A point, line, ray, or other segment that intersects a segment at its midpoint is said to bisect the segment. that point, line, ray, or segment is called a _____ ______?
segment bisector
formed by two rays with the same endpoint
angle
the _____ are the sides of the angle.
rays
the endpoint is the ______ of the angle.
vertex
angles with the same measure
congruent angles
two coplanar angles that have a common side and a common vertex but no common interior points.
adjacent angles
two angles whose sides form two pairs of opposite rays
vertical angles
two angles are CA if the sum of their measure is 90
complementary angles
two angles are supplementary if the sum or their measure is 180
supplementary angles
a pair of adjacent angles whose non-common sides are opposite rays
linear pair
a ray that divides an angle into two congruent angles
angle bisector
ruler with no marking
straightegde
geometrical toool used to draw circles and parts of circles called arcs.
compass
a geometric figure drawn using a straightedge and a compass
construction
two lines that intersect to form right angles
perpendicular lines
____ ______of a segment is a line, segment, or ray that is perpendicular to the segment at its midpoint
perpendicular bisector
a segment that connects two nonconsecutive verticles
diagonal
has no diagonal wot points outside the polygon
convex polygon
has at least one diagonal with points outside the polygon
concave polygon
the ______ of a polygon is the sum of the length of its sides
perimeter
______ of a polygon is the number of square units it encloses
area
a two dimensional diagram that you can fold to form a three dimensional figure .
net
The ____ between point a and point b is the absolute value of the difference of their coordinate
Distance
The ____ between point a and point b is the absolute value of the difference of their coordinate
Distance
Points that lie on the same lines
Collinear points
