To construct a rhombus given the lengths of its diagonals, you can follow these steps:

1. Draw the first diagonal: Using a ruler, draw a line segment of length 4.8 cm.
2. Draw the second diagonal: From one endpoint of the first diagonal, draw a line segment of length 6.3 cm. Make sure this line is not parallel to the first one.
3. The intersection of the two diagonals will be the center of the rhombus.
4. Draw straight lines connecting the endpoints of the first diagonal to the endpoints of the second diagonal. These lines will form the four sides of the rhombus.

By following these steps, you'll have constructed a rhombus with diagonals of lengths 4.8 cm and 6.3 cm.

To draw a parallelogram given the lengths of its adjacent sides, you can follow these steps:

1. Draw a line segment of length 2.8 cm. This will be one of the adjacent sides of the parallelogram.
2. From one endpoint of the first line segment, draw another line segment of length 3.8 cm. This will be the second adjacent side of the parallelogram. Make sure this line segment is parallel to the first one.
3. From the other endpoint of the first line segment, draw a line parallel to the second line segment, and from the other endpoint of the second line segment, draw a line parallel to the first line segment.
4. The intersection of these two lines will form the fourth vertex of the parallelogram.
5. Connect the vertices to form the parallelogram.

By following these steps, you'll have drawn a parallelogram with adjacent sides of lengths 2.8 cm and 3.8 cm.

To draw a rectangle given the lengths of its adjacent sides, you can follow these steps:

1. Draw a line segment of length 4.5 cm. This will be one of the adjacent sides of the rectangle.
2. At one endpoint of the first line segment, draw a line segment perpendicular to it of length 2.3 cm. This will be one of the adjacent sides of the rectangle.
3. From the other endpoint of the first line segment, draw a line parallel to the second line segment, and from the other endpoint of the second line segment, draw a line parallel to the first line segment.
4. The intersection of these two lines will form the fourth vertex of the rectangle.
5. Connect the vertices to form the rectangle.

By following these steps, you'll have drawn a rectangle with adjacent sides of lengths 4.5 cm and 2.3 cm.

To construct the quadrilateral ABCD with the given specifications, follow these steps:

1. Draw a line segment ABAB of length 4.3 cm. This will be one side of the quadrilateral.

2. At point BB, construct an angle of 105 degrees. To do this, use a protractor to measure and mark an angle of 105 degrees from line segment ABAB.

3. From point BB, draw a ray extending from the angle bisector of angle BB. This will be side BCBC.

4. Measure and mark a length of 5.2 cm along side BCBC. This will be point CC.

5. At point CC, construct an angle of 60 degrees. To do this, use a protractor to measure and mark an angle of 60 degrees from line segment BCBC.

6. From point CC, draw a ray extending from the angle bisector of angle CC. This will be side CDCD.

7. Measure and mark a length of 6.5 cm along side CDCD. This will be point DD.

8. Finally, draw a line segment connecting point DD to point AA.

By following these steps, you will have constructed the quadrilateral ABCD with the given specifications.

To construct the quadrilateral PQRS with the given specifications, follow these steps:

1. Start by drawing a line segment PQPQ of length 5.4 cm. This will be one side of the quadrilateral.

2. At point PP, construct an angle of 60 degrees. To do this, use a protractor to measure and mark an angle of 60 degrees from line segment PQPQ.

3. At point QQ, construct an angle of 105 degrees. To do this, use a protractor to measure and mark an angle of 105 degrees from line segment PQPQ.

4. From point QQ, draw a ray extending from the angle bisector of angle QQ. This will be side QRQR.

5. At point RR, construct an angle of 75 degrees. To do this, use a protractor to measure and mark an angle of 75 degrees from line segment QRQR.

6. From point RR, draw a ray extending from the angle bisector of angle RR. This will be side RSRS.

7. At point SS, construct an angle of 120 degrees. To do this, use a protractor to measure and mark an angle of 120 degrees from line segment RSRS.

8. Finally, draw a line segment connecting point SS to point PP.

By following these steps, you will have constructed the quadrilateral PQRS with the given specifications.
