Transcript Segment: - Father Ryan High School

Segment:
The set of points consisting of two points
called endpoints and all the points
between these points
Sides of an angle
► The
rays of an angle
Vertex
► The
common endpoint of the sides of an
angle
Distance:
The absolute value of the difference
of the coordinates for any two
points on a number line
Ray:
A ray, AB is the part of that AB that
contains point A and all points on
the same side of A as B
Opposite Rays
► Rays
that have the same endpoint and that
together make a line.
Postulate (or axiom):
A statement that is accepted as true
without proof
Congruent:
Figures that have the same size
and shape
Congruent segments:
Segments that have the same
length
Midpoint of a segment:
The point that divides the segment
into two congruent segments
Bisector of a segment:
A line, segment, ray, of plane that
intersects the segment at its
midpoint
Postulate 1
► Ruler
Postulate
► 1. The points on a line can be paired with
the real numbers in such a way that any
two points can have coordinates 0 and 1.
► 2. Once a coordinate system has been
chosen in this way, the distance between
any two points equals the absolute value of
the difference of their coordinates.
Postulate 2: Segment
Addition Postulate
If B is between A and C, then
AB+BC=AC
