Draw a circle with its two chords ^@PQ^@ and ^@RS^@ such that ^@PQ^@ is not parallel to ^@RS^@. Draw the perpendicular bisector of ^@PQ^@ and ^@RS^@. At what point do they intersect each other? 
Justify the steps of construction. 
 
                Answer: 
            
        - Draw a circle with any radius and center ^@O^@. 
- Draw two chords ^@PQ^@ and ^@RS^@. 
- With center ^@P^@ and radius more than half of ^@PQ^@, draw arcs on each side of the chord ^@PQ^@. 
- With center ^@Q^@ and same radius, draw arcs cutting the previous arcs at ^@A^@ and ^@B^@ respectively. 
- Join ^@AB^@. 
- With center ^@R^@ and radius more than half of ^@RS^@, draw arcs on each side of chord ^@RS^@. 
- With center ^@S^@ and same radius, draw arcs cutting the previous arcs at ^@C^@ and ^@D^@ respectively. 
- Join ^@CD.^@ ^@AB^@ and ^@CD^@ are the required perpendicular bisector of ^@PQ^@ and ^@RS^@ respectively. 
- Both perpendicular bisector ^@AB^@ and ^@CD^@ intersect each other at the center of the circle.
