Definitions:
Measures less than
90º
Drawing shows three
sides of an object in
one view, shows a
three dimensional solid
as a two dimensional
drawing
In a polygon, at least
one diagonal is on the
exterior of the
polygon. At least one
line that contains a
side contains interior
points.
A circle that touches
each side of the
polygon at exactly one
point
A segment that
connects two
nonconsecutive
vertices in a polygon
Lines that are in the
same plane that never
meet
An equilateral
parallelogram
The point of
concurrency for three
medians
The segment
connecting the vertex
of a triangle to the
midpoint of its
opposite side
Create a figure or real
life example that fits
your definition but
isn’t what you’re
trying to define
Two angles that share
a vertex and a common
side and their
noncommon sides
from a line
The point of
concurrency for three
angle bisectors
A line that intersects a
circle in exactly one
point
Angles formed by two
intersecting lines; they
share a common vertex
but not a common side
When three or more
lines have a point in
common
A parallelogram with
four congruent angles
On the same line.
The point of
concurrency for three
altitudes
A circle that passes
through each vertex of
the polygon
Share a common side
in a polygon
A ray if it contains the
vertex and divides the
angle into two
congruent angles
Consists of two points
called the endpoints of
the segment and all
points between them
that are collinear with
the two points.
The segment that
connects the midpoints
of two sides of a
triangle
The process of
showing that certain
statements follow
logically from agreedupon assumptions and
prove facts
Begins at a point and
extends infinitely in
one direction
An equilateral
rectangle, an
equiangular rhombus.,
a regular quadrilateral
The point of
concurrency for the
perpendicular bisectors
Measures more than
90º but less than 180º
The perpendicular
segment from a vertex
to the opposite side or
to a line containing the
opposite side
This process of
reasoning is the act of
coming to a general
conclusion from
particular facts
Lines that meet at 90º
angles
The longest chord of a
circle
A quadrilateral with
two pairs of parallel
sides
A line that intersects a
circle in two points
Two lines that do not
intersect and are
noncoplanar
A line, ray, segment,
or plane that passes
through the midpoint
of a segment
A quadrilateral with
exactly one pair of
parallel sides
Two segments are
congruent segments iff
they have the same
measure or length
The point on the
segment that is the
same distance from
both endpoints
This polygon has all
sides the same length
The generalization
made as a result of
inductive reasoning
In a polygon, all
diagonals are on the
interior of the polygon.
The lines that contain
the sides do not
contain the interior
points.
A segment whose
endpoints lie on the
circle
A quadrilateral with
two distinct pairs of
consecutive congruent
sides
A design can be
rotated around a point
by less than a full
circle and still look the
same.
