No, a scalene triangle, for example, is a convex poygon but it is not regular.
A convex polygon.I suspect that what you mean is a convex polygon.
The sum of the interior angles of a triangle is 180 deg. For a convex polygon with n sides we can divide it to n-2 triangles. So the answer, if the polygon is convex, is (13-2)*180= 1980 deg * * * * * The polygon need not be convex. The formula for the sum of the interior angles is valid as long as the polygon is simple - that it, its sides do not cross each other inside the polygon.
Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
Is a concave polygon.
A triangle.
No, a scalene triangle, for example, is a convex poygon but it is not regular.
The only convex polygon that is rigid is a triangle.
A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape. Think of it as a 'bulging' polygon. A triangle (3-gon) is always convex.
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.

360 degrees (this is true with any convex polygon)
A convex polygon with congruent sides and congruent angles is a regular polygon.Some regular pilgrims have specific names: Equilateral triangle and square

A convex polygon is a polygon such that no side extended cuts any other side or vertex; it can be cut by a straight line in at most two points Example: A square is a convex polygon, as is an eqilateral triangle. A star shaped polygon is NOT convex. More generally, In Euclidean space, objects are convex if for every pair of points within the object, every point on the straight line segment that joins them is also within the object.
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
