ABCD is parallelogram `vecA, vecB, vecC and vecD` are the position vectors of vecticles A, B, C, and D with respect to any origin, them:

ABCD is a parallelogram with A as the origin. vecb and vecd are position vector of B and D respectively. What is the position of vector C?

veca,vecb,vecc are the position vectors of vertices A, B, C respectively of a paralleloram, ABCD, ifnd the position vector of D.

veca,vecb,vecc are the position vectors of vertices A, B, C respectively of a paralleloram, ABCD, ifnd the position vector of D.

If veca, vecb, vecc, vecd are the position vectors of points A, B, C and D , respectively referred to the same origin O such that no three of these points are collinear and veca+vecc=vecb+vecd , then prove that quadrilateral ABCD is a parallelogram.

If veca, vecb, vecc, vecd are the position vectors of points A, B, C and D , respectively referred to the same origin O such that no three of these points are collinear and veca+vecc=vecb+vecd , then prove that quadrilateral ABCD is a parallelogram.

If veca, vecb, vecc, vecd are the position vectors of points A, B, C and D , respectively referred to the same origin O such that no three of these points are collinear and veca+vecc=vecb+vecd , then prove that quadrilateral ABCD is a parallelogram.

ABCD is a parallelogram with A as the origin. vecb and vecd are position vector of B and D respectively. If absvec(AC)=absvec(BD) , show that ABCD is a Rectangle.

ABCD is a parallelogram with A as the origin. vecb and vecd are position vector of B and D respectively.What is the angle between vec(AB) and vec(AD) ?

If veca,vecb,vecc,vecd respectively are the position vectors representing the vertices A,B,C,D of a parallelogram, then write vecd in terms of veca,vecb,vecc .

A, B, C and D have position vectors veca, vecb, vecc and vecd , repectively, such that veca-vecb = 2(vecd-vecc) . Then
