The width of an image divided by its height is known as the aspect ratio of the image.
the aspect ratio of a traditional TV screen is 4:3 but some high definition movies prefer the 16:9 standard.

Illustration of a geometric  transformation called "translation".

]]> <![CDATA[Translation / cable car]]>
This animation can be used to illustrate such concepts as translation, velocity, acceleration, and uniform and non uniform motion along a straight line.

Click and drag the mouse on the screen to create a vector which you can move to illustrate the translational motion.
]]> <![CDATA[Central symmetry]]>

Illustration of a geometric transformation called central symmetry.

]]> <![CDATA[Line symmetry]]>

Illustration of a geometric transformation called line symmetry.

]]> <![CDATA[Rotational symmetry]]>

Illustration of a geometric transformation called rotational symmetry.

]]> <![CDATA[Homothety]]>
The homothety is a transformation of space which dilates distance with respect to a fixed point O called the origin. The similitude ratio k is the number by which distances are multiplied. This ratio can be set  to negative values as well.

All objects in the animation can be moved  with a simple “click and drag”. The ratio k can be altered by clicking on the ratio and directly entering a new value.
]]> <![CDATA[Circular translation]]>

Example of translation along a circular path. Do not confuse this with rotational transformation.
