No. Convex simply means that if you have a straight line segment joining any two points in (or on) a convex shape, then every point on that line segment in inside or on the shape. A convex shape can have 2 or more dimensions, it can by a polygon or have curved sides.
900 degrees. And it does not have to be convex.
An interior angle of a convex heptagon can have any value in the range (0, 180) degrees.
Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
If it were a perfect heptagon then it would be convex. If it had any indentations then it would be concave.
A convex heptagon is one in which all the angles are smaller than 2*pi radians (180 degrees). An equivalent requirement is that a line joining any two points on or inside the heptagon cannot have any point that is outside the heptagon.
I think it is niether * * * * * A heptagon is simply a plane shape bounded by seven straight sides. Any polygon with three of more sides can be concave or convex.
900 degrees
A regular heptagon is a polygon with seven equilateral sides. The shape must also be equiangular and convex.
The sum of the angles is 900 degrees - and the polygon does not need to be convex.
Yes, but not a convex one.
seven There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles. There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles.
No convex polygon with 7 or more sides can tessellate.
