If all sides have equal lengths and all angles have equal measures what is it?

* square * equilateral triangle * or any of the other regular polygons having sides of identical length, e.g. regular pentagon, regular hexagon, regular octagon, etc


What is the area of a regular decagon having sides 7cm in length and a 19 cm apothem?

A=1/2aP a=19, P=70 (7*10) A=1/2(19)(70) A=1/2(1330) A=665 cm ^2


What are the attributes for a octagon?

The attributes for an octagon include having eight sides, eight angles, and all angles measuring 135 degrees. It is a polygon with equal side lengths and internal angles. The sum of the interior angles of an octagon is 1080 degrees, and it has rotational symmetry of order 8.


Where are there perpendicular lines in an octogan?

There are no perpendicular lines in a regular octagon. Perpendicular lines are found in squares and rectangles, where the angles are 90 degree angles. Regular octagons, unlike squares, have so many sides that the angles joining the sides cannot be as sharp as 90 degrees. Instead, the angles are much larger and the sides are much too wide apart to be anywhere near perpendicular. It is possible, however, to construct an irregular octagon having perpendicular lines.


What is the perimeter of a regular octagon with an area of 309.019336 square cm?

The regular octagon will consist of 8 congruent isosceles triangles each having equal angles of 67.5 degrees and an apex angle of 45 degrees. Equal sides are: square root of 309.019336*2/sin(45)*8 = 10.45250372 cm Base length: 10.45250372*sin(45)/sin(67.5) = 8 cm Perimeter: 8*8 = 64 cm

What is the perimeter of a regular octagon that has an area of 43560 sq ft?

A regular octagon is formed from 8 isosceles triangles, each having a base length of 'd' (the length of a side of the octagon) and base angles of 67.5°. The height of one triangle is, 1/2d.tan67.5 The area of one triangle is, 1/2(base x height) = 1/2d.1/2d.tan67.5 = 1/4.d2tan67.5 The area of the octagon = 8 x area of one triangle = 2d2tan 67.5 = 4.8284d2. Thus, 4.8284d2 = 43560 : d2 = 9021.5714 : d = 94.982 The perimeter = 8d = 759.86 ft. (2dp). Note : It can be shown that the area, A = d2(2 + 2√2).

What is the perimeter of a hexagon having 225 cm square area of a circle inscribed in it?

Area of circle = 225 cm2 implies radius = 8.46 cm (approx) Therefore, apothem of hexagon = 8.46 cm then side of hexagon = apothem*2/sqrt(3) = 9.77 cm (approx) and so perimeter = 6*side = 58.63 cm
