Geometry question. Picture attached below~! *When I added all the sides -I got a hexagon. @jim_thompson5910

jimthompson5910 (jim_thompson5910):

it is a hexagon since it has 6 interior angles (so 6 sides)

jimthompson5910 (jim_thompson5910):

what kind of hexagon and why?

OpenStudy (anonymous):

Does the sum of all angles determine if it's concave or convex? The rules are: *A convex hexagon = no angles pointing inwards & no internal angles can be more than 180°. *When any internal angle is greater than 180° = concave.

OpenStudy (anonymous):

The final sum is greater than 180, the angles it self are not.

jimthompson5910 (jim_thompson5910):

good, so are there any interior angles that are greater than 180 degrees?

OpenStudy (anonymous):

The sum of the angles ? Yes Each individual angle? No

jimthompson5910 (jim_thompson5910):

so because you don't have any individual angle over 180 degrees, that means you have a convex polygon

Thank for the clarification and help :)
