If you visit
Washington D.C.,
you might see this
five-sided figure.
What is……..
the Pentagon
This is the symmetry
this shape has.
What is……..
rotational symmetry
(180° rotation)
·
·
This polygon has
exactly one pair of
parallel sides.
What is……..
a trapezoid
This polygon differs
from a square only in
having different sizes
of angle sets.
What is……..
a rhombus
You would get this type of
line if you draw a
perpendicular line through an
isosceles triangle.
What is……..
symmetry
This is the point
where the sides of
an angle meet.
What is……..
a vertex
This is an angle that
measures between
90° and 180.°
What is……..
an obtuse angle
This is an accurate
measurement you will get by
measuring the angle below with
a protractor.
What is……..
°
75
This is what you would
draw if you wanted to
create a 155° angle with a
protractor.
What is……..
These are the estimated
measures of the numbered
angles in the diagram below.

This is a triangle
with one 90°
interior angle.
What is……..
a right
triangle
These are the measures
of the missing angles in
the diagram below.

This describes
why/why not a
regular octagon can
tile a surface.
What is……..
the interior angle of a
regular octagon is 135°.
135 is not a factor of 360
(can not add up to 360). It
can not completely
surround a point without
overlapping.
This is the measure
of the numbered
exterior angle 1 in
the diagram below.
138° 1
What is……..
42°
180° – 138° = 42°
This is the interior
angle sum for a
regular pentagon.
(And this is my
work/explanation.)
What is……..
°
540
(n-2) • 180 = angle sum
(5-2) • 180 = 540 °
or, 3 triangles • 180 = 540 °
This triangle has all
angle measures that
are less than 90°
What is……..
an acute
triangle
This triangle has no
sides of equal length.
What is……..
a scalene
triangle
What shape you can
make with three
sides with the lengths
12, 7, and 19.
What is……..
a straight line
or
not a triangle
This is what is true about
a triangle with only two
angles the same size; this
is the name of the
triangle.
What is……..
exactly two sides are
the same length. This is
an isosceles triangle.
This is the measure
of the missing angle.
48°
x
What is……..
66°
(180 – 48 = 132. 132 ÷ 2 = 66)
This is what is true
about the side
lengths of a
polygon in order to
build a rectangle
that is not a square.
What is……..
There are two pairs of
sides that are the same,
but all four sides are
NOT the same.
This describes whether or
not you can make two
different quadrilaterals with
the same 4 side lengths.
What is……..
you can make a different
quadrilateral with the same
side lengths if you change the
angles, or change the order of
the sides (if they are not all the
same length.)
This explains whether or
not the sides lengths 4, 7,
9, and 14 can make a
quadrilateral.
What is……..
the side lengths 4, 7, 9, and 14
can make a quadrilateral
because the three smallest
sides add up to more than the
fourth, largest side.
After you make your wager,
click on the ‘question mark’ for
your question.
This is the sum of the exterior
angles of a quadrilateral, and
how we know this.
What is……..
360°. We know this because
in order for the exterior
angles to go completely
around the quadrilateral,
they would have to make a
full rotation, 360°
This is a drawing of a
quadrilateral with one diagonal
that is a line of symmetry.
What is……..
(the diagonal in a square)
