POINT• Definition:
Names a
location and
has no size.
Represented
by a dot
PLANE• Definition:
Flat surface
that has no
thickness
and extends
forever.

R C
LINE SEGMENT
• Definition:
Part of a line
consisting of
two points
and all the
points
between
them.
A
B
ANGLE• Definition:
A figure formed
by two rays
or sides with
a common
endpoint
called a
vertex
PERPENDICULAR LINES
• Definition:
Two lines
meet (cross)
and create a
90 degree
angle.
PARALLEL LINES
• Definition:
Lines that lie in
the same
plane and
are the same
distance
apart over
their entire
length.
TRIANGLE• Definitio
n:
A closed
figure
with three
sides.
RIGHT TRIANGLE
• Definition:
A closed
figure with
three sides.
One angle
equals the
measure of
90 degrees.
PENTAGON• Definition:
A figure with
five sides.
HEXAGON• Definition:
A figure with
six sides.
SQUARE• Definition:
A four sided
regular
polygon with
four equal
sides and
angles.
Angles add up
to 90 degrees.
RECTANGLE
• Definition:
A four sided
figure
where all
interior
angles are
90 degrees.
TRAPEZOID
• Definition:
A
quadrilateral
figure which
has at least
one pair of
parallel sides.
PARALLELOGRAM
• Definition:
A
quadrilateral with
both pairs of
opposite sides
are parallel or
equal to each
other.
CIRCLE• Definition:
A line forming a
closed loop
every point
on which is a
fixed
distance
from the
center point.
CYLINDER• Definition:
The surface generated
by a straight line
intersecting and
moving along a
closed plane curve
while remaining
parallel to a fixed
straight line that is
not on or parallel to
the plane of the
directrix.
SPHERE• Definition:
A three-
dimensional
surface, all
points of
which are
equidistant
from a fixed
point.
CONE• Definition:The
surface generated by a straight line, the generator, passing through a fixed point, the vertex, and moving along a fixed curve, the
directrix.
OCTOGON• Definition:si
des are all the same length and whose internal angles are all the same size.
EQUALATERAL TRIANGLE
• Definition: An equilateral triangle is one in which all three sides are congruent.
