The interior angle measure of a regular polygon is calculated with the following formula, where n represents the number of sides or interior angles of the regular polygon.
angle= 180 (n-2)/n
determine the measure of the interior angles of a regular octagon and identify whether or not a regular octagon can be used as the only shape in a regular tessellation.

135°, no
135°, yes
144°, no
144°, yes

A 144

B no

Step-by-step explanation:

Decagon is a 10 sided figure

interior angle = 180 (n-2)/n where n=10

                        180*(10-2)/10

                          180*8/10

                          144

To tessellate, the angle must divide evenly into 360

360/144= 2.5

This is not evenly so it will not tessellate
