Naming & Constructing Geometric Figures
Vocabulary to Know
point – a location
in space shown
with a dot.
Name a point with
a letter.
.
segment – the
straight path
between 2 points.
Name a segment
with 2 endpoint
letters.

ray – a straight
path that has a
starting point and
goes on forever in
one direction.
Name a ray with 2
letters. The
starting point is
always the first
letter in the name.
line – a straight
path that goes on
forever in both
directions.
Name a line using
any two points on
the line.

angle – a figure
formed by 2 rays
or line segments
that share the
same endpoint.
vertex – the
endpoint where
the rays of the
angle meet.
vertices - plural
of vertex.
Name an angle
with 3 letters. The
vertex is always
the middle name.
.
polygon – a flat
figure made of
line segments.
The sides connect
in a closed path.
The sides do not
cross (intersect).
parallel – always
the same distance
apart; never
intersecting. There
can be parallel
lines, rays,
segments, planes,
sides…
right angle – an
angle whose sides
form a square
corner. It
measures 90˚ .
acute angle – an
angle whose sides
measure less than
90 .
obtuse angle –
an angle whose
sides measure
between 90 &
180 .
equilateral
triangle – a
triangle whose
sides are all equal
length.
quadrilateral or
quadrangle – a
4-sided polygon.
Name a
quadrangle by
listing, in order,
the names of the
4 vertices.
Names:
parallelogram –
a 4 s-ided figure
with 2 sets of
parallel sides.
regular – any
figure in which all
sides and angles
are equal.
rhombus – a
4-sided figure with
all sides the same
length and 2 sets
of parallel sides. It
can look like a
square or a
diamond.
trapezoid – a
hexagon – a
4-sided figure with 6-sided figure
one set of parallel
sides.
convex polygon
a figure in which
all sides are
pushed out.
concave polygon
a figure in which at
least one vertex
(corner) is pushed
in.
regular hexagon
a 6-sided figure
with all sides the
same length & all
angles the same
measure.
perpendicular
lines – lines or
segments that
intersect at right
angles.
Sample Test Questions:
1) Draw ray CD.
2) Draw ray JP so that
it intersects with line
segment WX.
3) Draw line RS
parallel to line MN.
4) Write 2 names for this
5) Riddle:
6) Riddle:
trapezoid using the letters.

sides.
Draw me and label my
vertices.

Figures that have the same size and
shape
