Algebraic sum of intercepts made by the plane x+3y-4z+6=0 on the axes is 

If $$OA$$ is equally inclined to $$OX, OY$$ and $$OZ$$ and if $$A$$ is $$\sqrt 3 $$ units from the origin then $$A$$ is

The distance between the points $$(-1,2,3)$$ and P is $$13$$. Then $$P=$$

The distance between the parallel planes given by the equations, $$\vec{r}.(2\hat{i}-2\hat{j}+\hat{k})+3=0$$ and $$\vec{r}.(4\hat{i}-4\hat{j}+2\hat{k})+5=0$$ is-

The number of octants in which $$Z$$ coordinate is positive is

If $$\overline { a } ,\overline { b } $$ are the position vectors of $$A$$ and $$B$$ then one of the following points lie on $$\overline { AB } $$

The distance between the points(4,3,7) and (1,-1,-5) is

If $$L, M$$ are the feet of the perpendiculars from $$(2, 4, 5)$$ to the $$xy$$-plane, $$yz$$-plane respectively, then the distance $$LM$$ is:

The name of the figure formed by the points $$(0, 0, 0), (1, 0, 1)$$ and $$(0, 1, 1)$$ is

The name of the figure formed by the points $$(3, -5, 1), (-1, 0, 8)$$ and $$(7, -10, -6)$$ is
