In fig. 28.7 if the coordinates of point `P\ a r e\ (a , b , c)` then Write the coordinates of points A, B, C, D, E and F. Write the coordinates of the feet of the perpendiculars from the point P 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`
