In a 'Right-Angled (90 degree)' triangle.
h^(2) = a^(2) + b^(2)
However, with suitable algebraic rearrangement, it can be made to work in any triangle.
There are a great number of different proofs of the Pythagorean Theorem. Unfortunately, many of them require diagrams which are hard to reproduce here. Check out the link to Wikipedia's page on the theorem for several different proofs.
you use the the 3 trigonometry functions , sin=opposite divided by hypotenuse cos=adjacent divided by hypotenuse tan=opposite divided by adjacent these are used to work out angles and side lengths in right angle triangles only!!! sine,cosine,tangent :)
His work on right angle triangles is known as Pythagorases Theorum and it states that.. "The square of the hypotenuse is equal to the sum of the squares of the other two side."
A rule of thumb is - the arc length should be the same as the diameter of the electrode. 3/32" electrode = 3/32" arc length. 1/8" electrode = 1/8" arc length etc. The thicker the electrode coating the shorter the distance from the end of the electrode to the work. Drag rods are contact rods. E-7024 is one.
== == meaning work hard
no only right triangles
No, only right triangles
All right-angles triangles. That is triangles that contain one angle at 90 degrees.

Yes. Heron's Formula works on all triangles.
Architects use triangles as part of their work in designing buildings. And finding the pygratheim therom and stuff.
Pyramid. Work: 4 sides (that you usually see) are triangles, the base (bottom) is a square
By tautology. If it did not work, it would not be a divisibility rule!
needs some double Ds for the rule to work:)
its to work out if two triangles are the same in every way
this question made me laugh so i shall answer it Well since triangles are the strongest shapes, many things are made of them. do you cross a bridge on the way to work? chances are its made of triangles.
If triangles have the corresponding sides congruent then they are congruent. SSS If two triangles have two sides and an included angle congruent then they are congruent. SAS If two triangles have two angles and an included side congruent then they are congruent. ASA SSA doesn't work.
