Find the sum of the two given vectors a and b. Since PQR forms a triangle, the rule is also called the triangle law of vector addition. Embedded content, if any, are copyrights of their respective owners. Notice that (u + v) + w and u + (v + w ) have the same magnitude and direction and so they are equal. Applying the triangle's law of vector to triangle OPT. Show Step-by-step Solutions Answer: Triangle law of vector addition states that when two vectors are represented as two sides of the triangle with the order of magnitude and direction, then the third side of the triangle represents the magnitude and direction of the resultant vector. One such method is “Triangle Law of Vector Addition”. So, we have The parallelogram rule asks that you put the tails (end without the arrow) of the two vectors at the same point, (just the a vector and b vector on the left of the diagram) then it asks you to close the parallelogram by drawing the same two vectors again (the b vector and a vector to the right of the diagram). It is a law for the addition of two vectors. Grounds for proving vector addition. Vector Addition is nothing but finding the resultant of a number of vectors acting on a body. Vectors can be added using the ‘nose-to-tail’ method or "head-to-tail" method. The vector $$\vec a + \vec b$$ is then the vector joining the tip of to $$\vec a$$ the end-point of $$\vec b$$ . This is the triangle law of vector addition. Triangle’s Law of Vector Addition. To add two vectors, make the initial point of the second vector coincide with the final point of the first, and then complete the triangle. Triangle Law of Vector Addition. $$\vec a\,{\rm{and}}\,\vec b$$ can equivalently be added using the parallelogram law; we make the two vectors co-initial and complete the parallelogram with these two vectors as its sides: Then, according to triangle law of vector addition, side OB represents the resultant of P and Q. Consider two vectors P and Q acting on a body and represented both in magnitude and direction by sides OA and AB respectively of a triangle OAB.
