Problem

The position vectors of the points A, B and C are (2i^+j^−k^)(2\hat{i} + \hat{j} - \hat{k}) , (3i^−2j^+k^)(3\hat{i} - 2\hat{j} + \hat{k}) and (i^+4j^−3k^)(\hat{i} + 4\hat{j} - 3\hat{k}) respectively. These points. (1) form an isosceles triangle (2) form a right angled triangle (3) are collinear (4) form a scalene triangle
