In fig. 28.7 if the coordinates of point `P a r e (a , b , c)`thenWrite the coordinates of points A, B, C, D, E and F.Write the coordinates of the feet of the perpendiculars from the pointP to the coordinate axes.Write the coordinates of the feet of the perpendicular from the point `P`on the coordinate planes `X Y , Y Z a n d Z Xdot`Find the perpendicular distances of point `P`from `X Y , Y Z a n d Z X-`planes.Find the perpendicular distances of the point `P`fro the coordinate axes.Find the coordinates of the reflection of `P`are `(a , b , c)`. Therefore `O A=a , O B=b n d O C=cdot`A. `a,b,c`B. `b,c,a`C. `c,a,b`D. none of these |

Answer» Correct Answer - C `PD,PE` and `PF` are the perpendicular distances of `P` from `XY,YZ` and `ZX`- planes respectively. We have `PD=OC=c,PE=OA=a` and `PF=OB=b` Hence, the perpendicular distances of `P(a,b,c)` from `XY,YZ` and `ZX` lanes are `c,a` and `b` respectively. |
