What do you call this shape??

It is a segment.  Look at below article.

They are round because that shape can withstand the most amount of pressure without exploding/collapsing. The shape is also called a pressure vessel.

Ellipsis (not to be confused with ellipse, which is a shape).

I asked that same question to my teacher last time. She told me that I have to Seperated the shape into different common shapes. (for example like lets say I wanted to seperate a "square" into some common shapes I could turn it into two seperate triangles or four different triangles. Well Just try to use the formulas you know for the areas of the different disected figures you get.

You are referring to locus/parametrics. The shape you are referring to in relation of a locus of a point and a line, is a PARABOLA. It looks like an curve/hill kinda thing.

Well, in geometry, a 20 sided shape is called a Icosagon, so 20x could be icosuple but I've never heard of that word!

Thick, stupid.  Did I just insult you?  Sorry!  Its also a type of triangle.

take a straw (cylinder) and ram it through a potato.  If you do it right, the straw will go right through the potato!  The cylinder is the strongest and most stable of the shapes and you can see why soups, veggies, fruits, etc. all come in cans!\n\nRight triangels, or right angles are all around you.  The floor and the wall of you room for example.  The bottom of a pool is a good example of an obtuse triangle, suspension bridges - trapezoid, if you look at the tip of a pencil - it's a cone but the shape of a cone when you look at it head on is a scalene triangle

It is called a meander or an oxbow.  Wikipedia has a good explanation.

Been a while, so I'm not sure what you're looking for exactly in "Geometric Shapes".. but these might help somewhat.\n\nSun/Plannets - Sphere\nTree Trunk - Cylindar\nPine Tree - Cone\n\n\n...and my brain stops working.  but just for humor's sake...\nGood Looking Woman - hourgalss\n\n=D good luck with the homework

called form of distortion is 'geometric distortion', which arises when a three-dimensional object is projected on a flat plane. For instance, a sphere in the image center is rendered as a round disk on the film, while a sphere in the image periphery of a lens with a large angle of view is elliptically elongated. \n\nExample: An Unnatural bowing of straight lines or other distortion of shapes, especially at the sides and corners in a TV picture.
