Bitruncatedicosadodecagon
Our first shape is a rare sight, it is of course, the Bitruncatedicosadodecagon, a funny newfangled somewhat jaggedy polygon, so called as it is an ordinary irregular Icosadodecagon with its corners truncated...twice!
It is a polygon that has 83 sides. It is an irregular
shape but if anyone can find an example of a regular
one then feel free to send it via trianglenet.blogspot@gmail.com
or text the URL to the number at the bottom of the page.
This is just one of the frankly endless possibilities of
a Bitruncatedicosadodecagon. It is a funny looking
specimen. An interesting shape to look at and find
out about. For more info go to www.shapesonline.org

What an odd shape!
Circle
Okay, so the Bitruncatedicosadodecagon was fun, now let's move on to something a bit more basic. A bit more...well...common. The humble circle. The circle is found a lot around the home. This picture depicts this:
This is a selection of common household objects.
The CD, a pair of glasses and a toy car. Can you
spot the circles?
The circle is indeed a common shape. Traffic lights, for instance, are round as are wheels and roundabouts. But what if it isn't perfectly circular?
Look at that egg just there. It is round, but not a circle.
This brings us onto our next shape. The Oval.
Oval
The egg is an oval shape, only 3 dimensional as apposed to 2 dimensional. Ovals are like circles, only taller and thinner. They aren't perfect circles, like rectangles aren't perfect squares, but it is round, like a circle. It also only has one side, one long round side around the circumference, like that of a circle too. Here are some examples of oval shapes:
This plate is an oval shape
The side of this building is oval shaped.
This German car ID sticker is oval shaped too.
What a lot of ovals!
Rectangle
The rectangle is an ordinary quadrilateral. It is a polygon, as all its sides are straight. It has two sets of parallel sides (two or more lines that would never meet no mater how long they are) and four sets of perpendicular sides (two lines that join together to form a right angle), something that round shapes cannot have as it requires straight sides. There is only one angle in any round shape and that is a big old 360 degree angle, despite it being so big and so obvious, most people don't even realise it's there! The entire shape is a 360 degree angle! But anyway, back to our rectangle, it has four sets of perpendicular sides and all the angles are right angles and, like all quadrilaterals, they all add up to 360 degrees. Remember, a right angle is always 90 degrees. Here are some rectangles:
These trampolines are rectangular
This ID plate is rectangular too
As is this computer screen
There are lots of examples of rectangles all around the home. In fact, 9 times out of 10 over 98% of domestic household items are in fact squares or rectangles!
Fancy that!
Square
The square is no more than a rectangle with all its sides the same length. In that case then most of the properties are pretty much the same. A square is only a square however, if all its sides are of equal length.
Here are some examples:
This window has square panes of glass
This checked flag is a square made of lots of smaller squares.
You callin' me square?
