A) parallel lines
B) coplanar lines
C) coincident lines
D) concurrent lines
Correct Answer: D
Solution :
Lines\[{{P}_{1}}=0={{P}_{2}};\,{{P}_{2}}=0={{P}_{3}};\]and\[{{P}_{3}}=0={{P}_{1}}\] are lines of intersection of planes \[{{P}_{1}}\] and \[{{P}_{2}}:{{P}_{2}}\] and \[{{P}_{3}},\,{{P}_{3}}\] and\[{{P}_{1}}\]respectively Therefore, the lines are non-coplanar and will intersect at unique point.You need to login to perform this action.
