Measure the distance of the diagonal (from one corner to the opposite corner) of the screen on your computer monitor to the nearest tenth of a centimeter or sixteenth of an inch. Measure the height of the screen along the vertical as well. Use the Pythagorean theorem to find the width along the horizontal
In your post, include the length of the diagonal, the width, and the calculations needed to determine the horizontal length of your computer monitor. After you have calculated the approximate length using Pythagorean theorem, use a measuring device to measure the horizontal length of your monitor. Was your measurement close? Why might the measurements not be exactly the same?
Typing hint: Type Pythagorean theorem as a^2 + b^2 = c^2. Do not use special graphs or symbols because they will not appear when pasted to the discussion board.

If it's a large flat plasma screen, I'd say it is approximately 42".
The simplest (and cheapest) way to determine the ACTUAL panel/screen size of your set is to get a tape measure (with inches on it, if you have one) and carefully measure the screen yourself (e.g. diagonally from top left corner to bottom right corner).
I presume everything in the set works as it should. Happy New Year.
Measure corner to corner diagonally. The numbers will match when you have it squared up.
If you need to square up a 2 piece desk, measure the desk, loosen the joint and add spacers as needed. Retighten the joint.
The checking of the frame rails for accident damage can be done easily. First place the vehicle over a flat clean cement floor. Select points on the frame rails such as front ends---suspension points---brackets attached to the rails on both sides and rear ends of rail. Make sure the points selected have a corresponding point on the other rail. Using a plumb bob drop the selected point to the floor and make a cross on the floor at that point. . Repeat the process for each selected point. The more points the easier to find where the rails are bent and by how much. Move the car out of the way and using a tape measure the distance diagonally between same points.-- EI-- from left hand front end to right hand rear end. Repeat the measuring from the opposite corners By measuring from one point on one side to the second point on the other side you will develop a continually crossing pattern of measurements. So in the end if you selected 4 points per side you will have 3 sets diagonal measurements on the floor or more . As you measure write the dimension on the floor. Now if there is a difference of more than 1/4 "(6mm)between any set of diagonals you will see if the rails are bent and if they are bent right or left or bowed in the middle. By measuring the heights of the corresponding points and recording them you will see if the rails are bent up or down. I understand it is a bit long winded but you will be in effect transposing the measurements of the points of the rails onto the floor so that the differences can be measured without the problems of items interfering with straight line distances.
That measurement, is measured on the DIAGONAL corner, to corner distance. It's NOT the actual measured width of the Viewing Screen. IT is only 1028mm Wide, but from corner to corner it's going to be..1070mm or 42 inches
If the diangonal of a square is 1, either side opposite the diagonal is equal to the sin of 45 degrees. sin 45=.70710678. The segments formed by the bisection of the diagonals would be one half the length of the diagonal which would be .5 x 1 = .5. Or you could take the sin of .70710678x.70710678=.5 for the bisectors.
(if I understand what you are asking.)
