When drawing a vector using the triangle method you will draw in the resultant vector using Pythagorean theorem. This is taught in physics.
By using the cosine rule in trigonometry the angles of the triangle can be worked out.
it depends on the method of subtraction. If the vectors are drawn graphically then you must add the negative of the second vector (same magnitude, different direction) tail to tip with the first vector. If the drawing is to scale, then the resultant vector is the difference. If you are subtracting two vectors <x1, y1> - <x2, y2> then you can subtract them component by component just like scalars. The same rules apply to 3-dimensional vectors
The difference is that the Isometric projection shows more and accurate drawing than the Oblique project which is just a pictorial method.
The term "rectangle method" is used in different ways in math, but I will guess that your question is related to finding areas on a Geoboard. A Geoboard has a grid of pegs; you can make outlines of figures by stretching elastic bands around the pegs. If your figure is a triangle, you can find it's area by making the smallest rectangle which will enclose the triangle (The rectangle should have vertical and horizontal sides). The area of the rectangle can be found easily by multiplying the length by the width. The area of the triangle is half of the area of the rectangle.
ASA is not a triangle, it is a method of proving that two triangles are congruent. ASA refers to showing that if two angles and a side (Angle-Side-Angle) of one triangle are the same measures as the corresponding angles and side of another triangle, then the two triangles are congruent. Since the three angles sum to 180 degrees, if two of them in one triangle are equal to the corresponding angles in the second triangle, then the third set of angles must also be equal. Consequently, ASA is equivalent to AAS and SAA. That is NOT The case with two sides and an angle, where it must be the included angle that is equal.

You describe the resultant computed using the graphical method by connecting the vectors head to tail. The difference from the tail of the first one to the head of the last one is the resultant vector. To determine resultant vector with the component method you use the formula x(squared) + y(squared) = R (squared).

by method of finding resultant
If you mean "What method is used to make a resultant vector into its components?" then the answer is called "resolution" and you can google it for details. If you mean "What method is used to detirmine a resultant vector?" well that one doesn't have a name as far as I know. Basically, you set up a visual representation of the forces and use trigonometry to find the length and direction of the resultant. Now, to find the resultant, you would draw a diagonal line. You can then make a triangle where one side has a length of 6 and the other 8. Because these two sides are at a 90 degree angle, you can use the pythagorean therum (a^2 + b^2 = c^2) to find the diagonal line which is the resultant vector. Hope this helps :) -Angelic Endeavor Minor Edit By Me: I had trouble formatting the pictures, I hope it works this time. Edit 2 By Me: I can't get the visual aid to work so you'll have to use your imagination, sorry. :(

You need two equations to use the addition method.
Column method can be used for both !
