Is angle a scalar or vector ?

Explanation

To determine whether an angle is a scalar or a vector, we can analyze its properties and definitions. Here's a step-by-step solution:

### Step 1: Define Angle
An angle (let's denote it as θ) is typically defined in terms of the arc length (s) and the radius (r) of a circle. The relationship is given by:
\[ \theta = \frac{s}{r} \]
where:
- \( s \) is the arc length,
- \( r \) is the radius of the circle.
