work out the exterior angle of a regular hexagon

Question

kymber · Answer

First you need to find the value of the whole thing. You know the formulerrr?

katielong · Answer

is it just 360/6 or is it something like n-2*180?

kymber · Answer

Yupp! it's (n-2)180
Then you take your answer and divide it by 6 to get the value of the interior angles.
Then you can take the value of an interior angle & subtract it from 180 to get the value of an exterior angle! :D

katielong · Answer

right so... (6-2)180...=4x180...=720...=total of interior angles?
720/6=80 so interior angles are 80
180-80=100 so exterior angles = 100

kymber · Answer

720 divided by 6 isn't 80! Try again :p

katielong · Answer

oh... sorry its 120 :L haha thanks though!

kymber · Answer

You're welcome! :D

ajprincess · Answer

sum of exterior angles of any regular polygon is 360.
to find the value of an exterior angle divide 360 by number of sides.

kymber · Answer

Oh, apparently there's an easier way u_u

katielong · Answer

nahh... that will  just confuse me even more!! :L

ajprincess · Answer

when u r askd to find the value of an interior angle use (n-2)180/n
and when u r askd to find the value of an exterior angle use
360/n.
