The polygon of seven(7) sides is named an 'HEPTAGON'.
For the given number of sides of other polygons, the prefix is
3 = tri ( trigon / triangle)
4 = tetragon ( rectangle/ quadrilaterial)
5 = penta
6 = hexa
7 = hepta ( as above)
8 = octa
9 = nona
10 = deca.
An equilateral figure means that the figure has all sides that are the same length.
A plane figure with 4 unequal sides is a quadralateral.
A shape with 7 sides.
A seven sided figure would be a heptagon. A Reuleaux heptagon, is a seven sided figure, but having constant diameter. [As seen in some British coins]. But a regular heptagon would have seven equal sides that were each straight.
inscribed angles
heptagon
It is a heptagon.
5Improved Answer:-An heptagon has 7 sides but a pentagon has 5 sides
Heptagon .
7
A Septagon from the greek Sept meaning 7
heptagon.
A plane figure with 7 straight sides
It is called a heptagon or a septagon,
A closed figure with seven sides is a "heptagon." It is sometimes also called a "septagon."
It is called a heptagon, from the Greek word for seven.
A polygon is a closed figure of three or more sides. A regular polygon is a figure with straight sides, each side of equal length and all internal angles equal to each other. 3 sides = triangle 4 sides = square 5 sides = pentagon 6 sides = hexagon 7 sides = heptagon 8 sides = octagon 9 sides = nonagon 10 sides = decagon
