# N-gon - examples

Examples of a regular polygon (polygon). Polygon is a closed part of the plane bounded by a broken line. Points which define a polygon are the polygon vertices. The number of vertices, sides and interior angles in a polygon is the same and this number specifies the name of the polygon: triangle, quadrangle, pentagon etc.- Inner angles

The inner angles of the triangle are 30°, 45° and 105° and its longest side is 10 cm. Calculate the length of the shortest side, write the result in cm up to two decimal places. - Regular n-gon

In a regular n-angle polygon the internal angle is 144 degrees. Find the number n indicating the number of sides of this polygon. - Kites

Boys run kite on a cable of 86 meters long. What is the kite altitude, if the angle from the horizontal plane is 77°? - N-gon

How many diagonals has convex 29-gon? - Octahedron - sum

On each wall of a regular octahedron is written one of the numbers 1, 2, 3, 4, 5, 6, 7 and 8, wherein on different sides are different numbers. For each wall John make the sum of the numbers written of three adjacent walls. Thus got eight sums, which also. - Tetrahedral pyramid

What is the surface of a regular tetrahedral (four-sided) pyramid if the base edge a=23 and height v=8? - Pentagon

Within a regular pentagon ABCDE point P is such that the triangle is equilateral ABP. How big is the angle BCP? Make a sketch. - Hexagon

Draw a regular hexagon inscribed in a circle with radius r=6 cm. What is its perimeter? - Hexagon

There is regular hexagon ABCDEF. If area of the triangle ABC is 19, what is area of the hexagon ABCDEF? I do not know how to solve it simply.... - Hexagon A

Calculate area of regular hexagon inscribed in circle with radius r=7 m. - n-gon

Gabo draw n-gon, which angles are consecutive members of an arithmetic sequence. The smallest angle is 70° biggest 170°. How many sides have Gabo's n-gon? - N-gon angles

What is the sum of interior angles 18-gon? What is the internal angle of a regular convex 18-polygon? - 6-gon

Perimeter of regular hexagon is 41. Calculate its circumradius (radius of circumscribed circle). - 9-gon

Sum of interiol angles of 9-gon is: - Octagon

We have a square with side 98 cm. We cut the corners to make his octagon. What will be the side of the octagon? - Regular 5-gon

Calculate area of the regular pentagon with side 11 cm. - Rotatable tower

Rotatable tower situated in the city center has ground shape of a regular polygon. If the tower is rotated by 15.652° around its centerpiece it looks from the side same. Your task is to calculate at least how many vertices can have a ground plan view of th - Polygon 42

Which polygon has 42 more diagonals than sides? - Tower

The top of the tower is a regular hexagonal pyramid with base edge 9.2 meters long and a height 9.6 meters. How many m^{2}of sheet is required to cover the top of the tower if we count 12% of the sheet waste? - Octagon from rectangle

From tablecloth rectangular shape with dimensions of 4 dm and 8 dm we cuts down the corners in the shape of isosceles triangles. It thus formed an octagon with area 26 dm^{2.}How many dm^{2}we cuts down?
