The octagon.
The rule is that as the number of sides of a regular polygon increases then the external angle decreases while the interior angle increases The summation of the interior and external angleof one vertex is 180o.
Triangle, square, hexagon.
Each interior angle of a regular hexagon measures 120 degrees. It has a total of 720 degrees of interior angles and a total of 360 degrees of exterior angles.
If the perimeter of the hexagon is 24 cm and it is regular, then each side has the same length, namely 24/6 or 4. Now that is also the length of each side of the octagon since they share a common side so its perimeter is 8x4=32 cm.
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
ANY n-sided polygon has interior angles that sum to 180(n - 2) degrees. For an octagon this is 180 x 6 ie 1080 degrees (so the individual interior angles of a regular octagon are 135 degrees).
If they are both regular polygons then it is the octagon which is 135 degrees whereas the hexagon is 120 degrees
Hexagon.
There are many regular polygons like the square, pentagon, hexagon, and octagon
Hexagon, square, equilateral triangle, octagon. Im 11 so hah
By themselves, only 3: triangle, square and hexagon. But there are combinations: eg octagon + square.
It is a regular octagon which has 8 sides
If it's interior angle is a factor of 360 then it will tessellate such as a square, a regular hexagon and an equilateral triangle.
Not necessarily. The definition of a polygon is a closed figure with straight lines and no curves. A "regular" polygon has to have equal side-lengths, such as a regular hexagon or a regular octagon.
The sum of the interior angles of a regular polygon is found with the formula: (n-2)180. For a regular octagon with 8 sides, the sum of the interior angles would be: (8-2)180 = 1080 degrees. This only works for regular polygons whose sides and angles are congruent.
That could be numerous polygons: a square, a regular hexagon, a regular octagon, a regular dodecagon ... Any regular polygon with an even number of sides could be your answer.
the Square and the ParallelogramIf there can be more sides then an y of the regular polygons with an even number of sides fill the bill: regular hexagon, octagon, decagon...
Triangle, square, hexagon.
