Determine the nature of the quadrilateral formed by four lines `3x+4y -5=0, 4x-3y-5=0; 3x + 4y - 5 = 0 and 4x-3y + 5 = 0` Find the equation of the circle insc quadrilateral inscribed and circumscribing this quadrilateral.

Explanation

To solve the problem, we need to determine the nature of the quadrilateral formed by the four given lines, and then find the equations of the inscribed and circumscribed circles.

### Step 1: Identify the lines and their slopes
The given lines are:
1. \( L_1: 3x + 4y - 5 = 0 \)
2. \( L_2: 4x - 3y - 5 = 0 \)
3. \( L_3: 3x + 4y - 5 = 0 \) (which is the same as \( L_1 \))
4. \( L_4: 4x - 3y + 5 = 0 \)
