things about lines, segements,points,etc.. basic stuff
point
a location
has no shape or size and always uses capital letter
line
a line is made up of infinte points but any two points contain one line
has no thickness or length
collinear points
points that lie on the same line
non-collinear points
points that do not lie on the same line
plane
a 2d shape that has a flat surface and is made up of points
any 3 noncollinear points make up a plane
extends in all directions for infinity
coplanar points
points that lie on the same plane
noncoplanar points
points that do not lie on the same plane (must be at least four points)
segment addition postulate
the length of a line segment divided into smaller pieces is the sum of the lengths of all those smaller segments
segment bisector
line or ray that passes through the seg. Midpoint of another line segment dividing the line into 2 equal parts
a line, ray, or segment that intersects a segment at it’s midpoint is said to…
ray
has a beginning but no end ( goes on for infinity)
congruent segments
line segments that have the same length
line segment
connects 2 points and has a beginning and an end
postulate
a claim that is accepted to be true without proof
to assume a claim as true, necessary, or existent
midpoint
a point that divides the segment into 2 separate congruent segments
