OBJ: You will be able to find the sum of the measures of the interior and exterior angles in any -gon
Archaeologist Ertha Diggs has uncovered a piece of a ceramic 2. ABCDE is a regular pentagon. ABFG is a square. What is the
plate. The original plate appears to have been in the shape

of a regular polygon. If the original plate was a regular 12gon, it was probably a ceremonial dish from the third
century. If it was a regular 18-gon, it was probably a palace
dinner plate from the twelfth century. Ertha measures each
of the sides of her piece and finds that each side has the
same length. She then conjectures that all the sides of the
original whole plate had the same length. She measures
each of the angles of her piece and finds that they all have
the same measure. She then conjectures that all the angles
of the original whole plate had equal measures. If each

̅̅̅̅ is the side of an equilateral triangle. ̅̅̅̅ is the side of a
square. ̅̅̅̅ is the side of a regular pentagon. ̅̅̅̅ is the side
of a regular hexagon. ̅̅̅̅ is the side of a regular octagon.
Find the following angle measures.

Three regular polygons meet at point A. Only four sides of
the third polygon are visible. How many sides does this

a)
Notice that the sum of the three angles surrounding
point A sum to 360. Find 3 different regular polygons
such that the sum of an interior angle from each totals
360 similar to the problem above.
b) Repeat part a) but this time find 4 different regular
polygons such that the sum of an interior angle from
each totals 360.
