Construct a rhombus pqrs with each side of length 4.5 cm and one diagonal of length 6 CM show this in diagrams

To construct a rhombus \(PQRS\) with each side measuring \(4.5 \, \text{cm}\) and one diagonal measuring \(6 \, \text{cm}\), you can follow these steps:

### Step-by-step Construction

1. **Draw Diagonal PR:**
   - Draw a line segment \(PR\) of length \(6 \, \text{cm}\). This will be one of the diagonals of the rhombus.

2. **Find the Perpendicular Bisector of PR:**
   - Since the diagonals of a rhombus bisect each other at right angles, find the midpoint \(O\) of \(PR\). 
   - Draw a perpendicular bisector of \(PR\) through the midpoint \(O\).

3. **Determine Length of Diagonal SQ:**
   - Let the other diagonal be \(SQ\), and since it bisects \(PR\), it creates two right triangles \(POS\) and \(QOR\).
   - Using the Pythagorean theorem in one of the right triangles, we have:
     \[
     \left(\frac{SQ}{2}\right)^2 + 3^2 = 4.5^2
     \]
     Solving for \(SQ\), we get:
     \[
     \left(\frac{SQ}{2}\right)^2 = 4.5^2 - 3^2
     \]
     \[
     \frac{SQ}{2} = \sqrt{4.5^2 - 3^2}
     \]
     \[
     SQ = 2 \times \sqrt{4.5^2 - 3^2} \approx 5.66 \, \text{cm}
     \]

4. **Draw Diagonal SQ:**
   - Measure \(SQ \approx 5.66 \, \text{cm}\) and mark points \(S\) and \(Q\) on the perpendicular bisector such that \(O\) is the midpoint of \(SQ\).

5. **Complete the Rhombus:**
   - Connect \(S\) to \(P\) and \(R\), and \(Q\) to \(P\) and \(R\) to form the rhombus \(PQRS\).

### Diagram

Here is the diagram illustrating the construction:

In this diagram:
- \(PR = 6 \, \text{cm}\) is the given diagonal.
- \(PQ = QR = RS = SP = 4.5 \, \text{cm}\) are the sides of the rhombus.
- \(SQ \approx 5.66 \, \text{cm}\) is the other diagonal.

This method uses the property that the diagonals of a rhombus bisect each other at right angles and divides each diagonal into equal halves.
