The following is an example of an irregular polygon http://curriculum.kcdistancelearning.com/courses/GEOMx-HS-A09/a/assessments/Semester1Exam/Geometry_SemesterA_Final_209q.gif
okay, thats true its very irregular ;p is there a question ? :)
oh. sorry. true or false
regular polygon will have all sides equal. do u think the given polygon has all sides equual ?
lol sure! *wink wink*
are all angles equal ?
no they are not
some angles are acite, some are obtuse... and nothing seems to be equal there
so its not regular
its an irregular polygon
ok i have another question
shoot
is this an example of a concave polygon? http://curriculum.kcdistancelearning.com/courses/GEOMx-HS-A09/a/assessments/Semester1Exam/Geometry_SemesterA_Final_214q.gif
look at the angles, few angles are > 180 eh ?
so its concave , true
ok. im awful with these???
To calculate the sum of the interior angles of a polygon multiply the number of sides by 180° Answer True False
wat do u think ha
|dw:1374297400640:dw|
triangle is a polygon it has 3 sides multiply 3 x 180 = 540 but we know that its false, cuz sum of angles equal 180 in a triangle
so its False
oh yah. (n-2)180/2=
is that the right equation?
(n-2)180/n
its just : (n-2)180
