Let `ABC` be a triangle, the position vectors of whose vertices are respectively `hati + 2hatj + 4hatk, -2hati+ 2hatj + hatk and 2hati+ 4hatj-3hatk`. Then `Delta ABC` is

Let ABC be a triangle the position vectors of whose vertices are respectively hati+2hatj+4hatk, -2hati+2hatj+hatk and 2hati+4hatj-3hatk . Then the /_\ABC is (A) isosceles (B) equilateral (C) righat angled (D) none of these

Let ABC be a triangle, the position vectors of whose vertices are respectively 7 hatj + 10 hatk , -hati + 6 hat j + 6 hatk and -4 hati + 9 hatj + 6 hat k . " Then, " Delta ABC is

Find the vector area of the triangle, the position vectors of whose vertices are hati+hatj+2hatk, 2hati+2hatj-3hatk and 3hati-hatj-hatk

If the position vectors of the vertices of a triangle of a triangle are 2 hati - hatj + hatk , hati - 3 hatj - 5 hatk and 3 hati -4 hatj - 4 hatk , then the triangle is

If the position vectors of the vertices of a triangle be 2hati+4hatj-hatk,4hati+5hatj+hatk and 3 hati+6hatj-3hatk , then the triangle is

The position vectors of the points A, B, C are 2 hati + hatj - hatk , 3 hati - 2 hatj + hatk and hati + 4hatj - 3 hatk respectively . These points

The position vectors of the points A, B, C are 2 hati + hatj - hatk , 3 hati - 2 hatj + hatk and hati + 4hatj - 3 hatk respectively . These points

The position vectors of the points A, B, C are 2 hati + hatj - hatk , 3 hati - 2 hatj + hatk and hati + 4hatj - 3 hatk respectively . These points

If the position vectors of A and B respectively hati+3hatj-7hatk and 5 hati-2hatj+4hatk , then find AB

If a=3hati-2hatj+hatk,b=2hati-4hatj-3hatk and c=-hati+2hatj+2hatk , then a+b+c is
