What are the names of the shapes with 4, 5, 6, 7, 8, 9 and 10 sides called and what do they look like?
Answers:
4.quadrilatreal
5.pentagon
6.hexagon
7.heptagon/septagon
8.octagon
9.nanogon
10.decagon
square/rectangle, pentagon, hexagon, heptagon, octagon, nonagon and decagon.
The names of all polygons with up to 100 sides are shown at http://home.comcast.net/~igpl/nwg.html.
4 sides - tetragon
5 sides - pentagon
6 sides - hexagon
7 sides - heptagon
8 sides - octagon
9 sides - enneagon
10 sides - decagon
Regular Polygons are shown at http://www.ul.ie/~cahird/polyhedronmode/.
Hi 6 is a hexagon and looks like a stop sign. 5 looks like, well, the Pentagon. Get the idea?
If you mean 2 D shapes:
4 quadrilateral
5 pentagon
6 hexagon
7 heptagon
8 octagon
9 nonegon
10 decagon
To be regular shapes all the sides have to be of equal lenght and the internal angles have to be equal.
quadrilateral,pentagon,hexagon. respectively
4 quadrilateral
5 pentagon
6 hexagon
7 heptagon
8 octagon
9 nonagon
10 decagon
well one term could cover all those.. polygon
the 4 sided, add trapezoid (think of a triangle with the top taken off
Are they solids --> http://www.jimloy.com/geometry/hedra.htm.
or plane objects --> http://www.mathsisfun.com/shape.html?.
Lots of good answers so far.
As to what they look like -
Grab 10 toothpicks (or similar objects).
Take the number of toothpicks you want for the shape you want (for example: 6 for a hexagon) and put them together end to end, such that -
1) each end connects with another toothpick's end
2) no toothpicks cross
3) there are no toothpicks angled towards the inside of the shape.
A great kid's project too, provided they don't eat the toothpicks :)
4. tetragon or quadrilateral
a four-sided polygon
5. Pentagon
A polygon with five sides and five angles.
6. hexagon
A flat figure with six angles and six sides
7. heptagon
a heptagon is a polygon with seven sides and seven angles.
8. octagon
an octagon is a polygon that has eight sides.
9.nonagon
A polygon with nine sides
10. decagon
a polygon with 10 sides and 10 angles
They are called polygons, and your answer is already given by others.
