A convex polygon.I suspect that what you mean is a convex polygon.
There are six triangles in an octagon. In any convex polygon, there are two less triangles than the number of sides. So a octagon which has 8 sides, contains 6 triangles.
ConvexA convex polygon does not have a "dent" in it.
Yes, an octagon is a polygon that has eight sides.
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.

is this a polygon? is it concaver or convex
The measure of the exterior angle of a convex octagon is indeterminate.
A convex polygon, including an octagon, is a 2d shape such that any straight line joining any two points on its boundary lies wholly within the shape. This is assured if each of its interior angles is less than 180 degrees.
a polygon is convex
an octagon is a polygon. an octagon has 8 sides. a polygon is a shape with closed sides.
If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon. If it is not a regular octagon (i.e. if it is an irregular octagon) then is it an irregular polygon.
An 8 sided polygon is an octagon
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.
It can be but need not be.
It is convex if you look at it from the inside but it is not any kind of polygon.
Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
Is a concave polygon.
A convex polygon.
A polygon is convex if you can take any two points inside the polygon and connect them with a line segment that is completely contained by the polygon. A non-convex polygon is one which contains at least two points such that the line joining them does not lie entirely inside the polygon.
No interior angle of a convex polygon can exceed 180 degrees. A non-convex polygon has at least one reflex angle (> 180 degrees). Alternatively, a polygon is convex if, given any two points on or inside the polygon, the straight line joining the two points must lie wholly on or inside the polygon. In a non-convex polygon, it is possible to find a pair of points such that the straight line joining them lies outside the polygon for at least some of its length.
