Hi i am Jo would need help in finding the length of the third side of a triangle in excel I have three points number: AB- 235 BC- 156 need to find length AC - it's not a right angle triangle,

Welcome to the forums Jo. Having the length of two sides of a triangle isn't enough to calculate the length of the 3rd side, for a non right-angle triangle. You'll also need to know one of the angles.

Thanks Iain for getting back/ Iain and i am trying to format it in Excel, isn't it possible based on the chart where it has an X and Y axis too

I don't understand what you mean unfortunately - can you please take a screenshot of the problem, as that may help me see what you're trying to achieve .

I have drawn lines in excel, any options in excel where it can evaluate the axis and evaluate the length of the third side. Eg: if i draw the same line in the piece of paper it's easy. anything possible in excel.

What's the X axis measurements? It just says 1,2 and 3 - which I guess isn't a real value (or is it)? Your "triangle" has lines that cross almost 200 units on the Y axis, but only 1 or 2 units on the X axis. Is this data coming from cells somewhere?

I don't know what A, B and C are - it's just numbers. AB is the difference between A and B, but isn't the line length on that graph you've drawn, it's just the difference in height. Same for CB. If you can explain where you've got this from, I may be able to help.

Ian EG: DJI daily data the analysis formulates the base high /low and buy /sell prices setting targets and stop loss. the base high low is flowing in a triangular format, to analyse it better I am after the third line. attached is the pic . its very good I believe

Sorry @JSK, I'm not sure how to do what you're asking as don't see how it's possible to calculate the numerical length with that information - it may be worth asking some traders, as it sounds fairly specific to that. Sorry I can't be of more help.

Thank Ian for your time and reference. I was thinking more from the maths point of view, doesn't matter stocks or just normal length.
