Question

state the triangle law and parallelogram law for vector addition

Answer 1

Answer:

The parallelogram law of vector addition : If two vectors acting simultaneously on a particle are represented in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point, then their resultant is completely represented in magnitude and direction by the diagonal of that parallelogram drawn ..

may help you

Answer 2

The Triangle Law of Vector Addition states that "If two similar vectors can be represented both in magnitude and direction as two sides of a triangle taken in order, then the third side taken in the reverse order gives the resultant of two vectors both in magnitude and direction..."

The Parallelogram Law of Vector Addition states that "If two similar vectors can be represented both in magnitude and direction as two adjacent sides of a parallelogram with origins at the intersection, then the diagonal from the point of intersection gives the resultant of the two vectors, both in magnitude and direction..."

The Polygon Law of Vector Addition states that "If a number of vectors can be represented as the sides of a polygon taken in order, both in magnitude and direction, then the side which completes the polygon taken in the reverse order, gives the resultant of all the original vectors both in magnitude and direction..."
