# Rectangle Symbols & Alt and HTML Codes

A rectangle is a four-sided shape, and all the angles are right angles. If you want to figure out if a shape is a rectangle, you have two tests. Is it four-sided? And, are all the angles 90 degrees? If both answers are yes, then you're looking at a rectangle.

Rectangles have a few special features. First, the opposite sides are parallel. Second, the opposite sides are equal in length. In the rectangle shape, if we know the side, AB is parallel to side CD, and BC is parallel to AD. Also, if we know AB is six, then so is CD. If BC is four, then so is AD.

### How to use and type Rectangle symbol code?

• If your keyboard contains separate NumPad, you should be sure that it is enabled. If it is not, press the Num Lock key to activate it then press hold down the Alt key on the left side. Type the number that represents that character or the symbol you want to insert and then release the insert key.
• For example, for the greek letter omega Ω press and hold Alt and the type 0234 and then release.
• There is another method that works only for word documents. In this method, you should type the characters first then press Alt and X. For example ( 0234 + Alt + X for greek letter omega ).
• If you have a keyboard that doesn't have NumPad here is what will work for you. Find the Function key ( FN ) then presses and hold the function key while holding press and release Num LK key; then release FN key. This method will activate the numeric keypad in your laptop.
• Then do the same steps as in the previous example.
• Notice that in IBM code you don't use 0 (Alt + 255 ) before the code which is different from the windows generator that requires to add 0 (Alt + 0255 ) before the code.
