D) none of these can be used to tile the plane
Feedback: Correct!
5
CORRECT
Which statement is correct?
A) A regular octagon can be used to tile the plane.
B) A regular octagon cannot be used to tile the plane, since the measure of one interior
angle does not divide evenly into 360º.
C) A regular octagon cannot be used to tile the plane, since the measure of one interior
angle does not divide evenly into 180º.
D) A regular octagon cannot be used to tile the plane, since the measure of one interior
angle does not divide evenly into 720º.
Feedback: Correct!

9
CORRECT
Elzbieta has two square tiles and two equilateral triangle tiles that all have the same side length.
Which statement is true?
A) These cannot be joined at a point to form a tessellation because the interior angles do
not add to 360º.
B) These can be joined at a point to form a tessellation because both are regular polygons.
C) These can be joined at a point to form a tessellation because the interior angles add to
360º.
