I know there are 6 sides so i would have to start with that.

OpenStudy (perl):

how many triangles can you form from this shape?

OpenStudy (anonymous):

4?

OpenStudy (anonymous):

wait, 6 sides, you can form 4 triangles with those 6 sides, 4 times 180 would be 720?

OpenStudy (anonymous):

@perl, is this right?

OpenStudy (perl):

yes !!! you got it

OpenStudy (anonymous):

Thanks so much!

OpenStudy (perl):

each triangle has 180 degrees in the interior , so 4 * 180
