pythagora question

[Golf1.6]

I've looked up numerous pythagoras calculators online all of them are able to give me the angles and length of the hypothenuse, if I provide 2 sides. But none seem to be able to give me the lengths of 2 sides if I know the length of a and angle of a with c.

Is this possible?

No. One angle and one line length isn't enough to define a triangle.

EDIT ... what efour said below. I misunderstood your question.

 

[Efour]

well the other angle you need is 90 degrees then you can do it like i used to do it at age 10 ???

rearrange it to what you need..

 

[Snookums]

if youve got the side a and angle b or c then you can use either the sine or cosine rule i believe give them a google and find a tutorial how to use them

No. One angle and one line length isn't enough to define a triangle.

However, one right angle, one other angle and one length is enough to define a triangle, which is presumably what Golf is referring to since he is talking about Pythagoras.

What you will need is some basic trigonometry, specifically what is often remembered as sohcahtoa (give it a google).

or ask most 11 year olds who go to non-***** schools

sorry yes, pythagoras only works with triangles with one right angle. So i know TWO angles, one custom angle, 1 right angle and 1 side.

why exactly do you need an online calculator for this?

you could always knock one up yourself in excel

Why do you need an online calculator? Just get a pen and paper and do it yourself.

Well, I think you'll find it's hippopotamus

thanks, had such a doh moment, because I just did trial and error a week ago, playing around with side b until the angle of a matches to what i have.

I used this http://jumk.de/pythagoras/pythagoras.shtml

It's for a garden outhouse that's hexagonal shape so I've been pulling hairs out with my planning, not know what mitre cuts to do.

dont get my started on the roofing either.

 

[AHarvey]

Design anything like that in Sketchup and then use it as a reference for cutting lists

 

[itchy]

Just get a rectangle outhouse problem solved.

What are you talking about? It's clearly Harry Potter news.

The mitre (cut) angle for a hexagon is 60 degrees, no need for trig.

The mitre (cut) angle for a hexagon is 60 degrees, no need for trig.

Only if it's a regular hexagon.
