a and d are parallel. a and b , b and d are perpendicular.
Given information:
Given,
Calculation:
The vectors are
The magnitudes of the vectors are:
The absolute value of dot products are given by:
From the above:
Hence, a and d are parallel.
Also, the dot product of a,b and b,d are 0.
Hence, a and b , b and d are perpendicular.
Conclusion:
a and d are parallel. a and b , b and d are perpendicular.
