•WHAT IS THE ANGLE BETWEEN a and -3a/2, The answer for this question will be 180°.
•The first vector is 'a',This means the vector's magnitude is a and the vector is in positive direction.
•The second vector is -3a/2, This means the vector's magnitude is 3a/2 and the vector is in negative direction.
•The first vector is in positive direction and the second vector is in negative direction. Therefore, THE ANGLE BETWEEN a and -3a/2 is 180°.

Angle between a and -(3/2)a is 180° (If they meet at a point), else, the angle is Undefined.
Given data : 2 lines a, -(3/2)a
Computation :
- a is positive. So, we can say that it is going through postive axis.
- -(3/2)a's magnitude is 3/2 times the magnitude of a.
- So, It is clear that -(3/2)a is going through negative axis.
- As a and -(3/2)a are anti-parallel or opposite to each other, the angle between them will be 180, If they are in a line and ever met.
- If they are parallel and never met with each other at a point, the angle between them is said to be undefined.
