Turn the paper sideways. Put your finger on the top corner of the ruler. Put that corner on the BOTTOM left corner of the paper. Press the ruler hard onto that corner. Now, swing the other end of the ruler UP to the right TOP corner of the paper. HOLD both ends of the ruler in place. Look at the ruler measurement. Write it in whole number and fraction as you read it from the ruler.
in a square it is the side length radical 2
Measure from one corner to the diagonal corner, and then switch and measure the other 2 diagonal corners. If the measurements are the same, then the walls are at right-angles to each other.
when starting from a wall you first need to make sure the wall is square to perfect. use the 3-4-5 method to find the perfect square-- this will tell you if the wall is perfectly squared or not. In this case I will be starting with my right shoulder-- Stretch your tape measure and point the metal tip into the eight side corner of the room. now measure out to the left 3 feet and make a mark at the 3 ft. point with a magic marker or pencil. now measure from the corner along the wall down to a 4 foot mark and mark a 4 ft. point now measure diagonally from the 3 foot point to the 4 foot point and you should have a 5 feet reading-- if you have a 5 ft reading then you found the perfect square starting point and now cut a tile in a diagonal / half and set it in the corner of your calk line square. The rest is way too indepth so my advice is to "GOOGLE" How to lay ceramic tile to find your favorite how to video. Good luck.
it depends on what you mean by a diagonal. If you take a diagonal to mean a line from one corner to the "opposite" corner, then a nonagon doesn't have any, and a decagon has five. The reason a nonagon doesn't have any, is that the corners aren't opposite each other.

The same way you measure a TV screen, diagonally (any corner to opposite corner).
Measure diagonally with a tape measure from corner to corner of the viewable area only. Doesn't matter if you start on the top corner or the lower corner.
If you mean a TV's actual size, you measure the screen diagonally
Diagonally, from the top corner to the opposite bottom corner.
Kitty corner, which is used in the U.S. to mean diagonally opposite is a corruption of cater-corner. Cater itself is an obsolete word meaning four. Compare the french quatre.
It is still customary to measure, in inches, a screen from corner to corner diagonally.
there is many different sizes, they are measures by the screen , the most common ones are : 15" and 17"
Diagonally yes
The 'long' diagonals are those two that run from one corner square diagonally across the board to the square in the opposite corner. They are the diagonals a1-h8 & h1-a8.
With the wall laying flat, measure diagonally from corner to corner both ways. Adjust the wall until these measurements are exactly the same. At that point you have a square wall. Either sheet the wall or run a piece of lumber diagonally from corner to corner nailing it to each stud, this will hold the wall square when it comes time to stand it up. Hope this helps

A monitor's size is the distance (usually measured in inches) from corner to corner, diagonally across the screen.This applies to widescreen and normal/full screen monitors.However the manufacturer's specified size might be slightly more than the actual 'viewable size' for a couple of reasons:1. They tend to round-up. So what they might call a 24 inch monitor might actually only be 23.5 inches.2. A CRT monitor's size traditionally includes the casing around the screen, for reasons dating back to the invention of the technology decades ago. This doesn't apply to lcd flat panel monitors.See the related link(s) for a more indepth guide and a tool for getting an approximate measurement of a monitor screen size.By Measuring the monitor diagonally this will give you the screen size.The specific models of the laptops usually have uniform sizes of the screens. So, if you know the model number, you can very easily look up its screen size.
