which expression represents the number of sides in the polygon for the nth member of the pattern?
97188
Explanation: The solution is n + 2. This expression represents the number of sides for the nth polygon in this pattern. For any value of n, you can use this expression to determine the number of sides.

The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180. If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.

In five dimensions, they are: The 5-simplex of the simplex family, {3,3,3,3}, with 6 vertices, 15 edges, 20 faces (each an equilateral triangle), 15 cells (each a regular tetrahedron), and 6 hypercells (each a 5-cell).

You can see that there are seven lines of symmetry, and the regular heptagon also has rotational symmetry order seven. The order of rotational symmetry and the number of lines of symmetry of any regular polygon is equal to the number of sides.

To find the perimeter of a regular hendecagon you must first know the number of sides in a hendecagon is 11. When you know the number of sides of a regular polygon to find the perimeter you must multiply the side length by the number of sides. In this case it is .

Finding the Number of Sides of a Polygon You can use the same formula, S = (n − 2) × 180° S = ( n - 2 ) × 180 ° , to find out how many sides n a polygon has, if you know the value of S , the sum of interior angles. The unknown shape was a heptagon!

In Euclidean plane geometry, a quadrilateral is a polygon with four edges (sides) and four vertices (corners). ... The word "quadrilateral" is derived from the Latin words quadri, a variant of four, and latus, meaning "side".

If you think about that, it means that a triangle is a polygon. So are squares, rectangles and, yes, quadrilaterals, parallelograms and trapezoids. They all are closed shapes with many sides, so they're all polygons!
