How do you construct a parallelogram with diagonals measuring 54cm and 62cm, with an angle of 70 degrees between them?

To construct a parallelogram given diagonals and the angle between them, follow these steps:

  1. Understanding dimensions: The diagonals of the parallelogram are 54 cm and 62 cm.
  2. Setting up your tools: You will need a ruler, a compass, and a protractor.
  3. Drawing the first diagonal: Use your ruler to draw a line segment of 54 cm (this will be diagonal AC).
  4. Finding the midpoint: Mark the midpoint of this segment, label it O.
  5. Drawing the second diagonal: From point O, draw a line of 62 cm at an angle of 70 degrees to the first diagonal (AC). Use your protractor for accuracy (this will be diagonal BD).
  6. Labeling points: Label the ends of the second diagonal as B and D.
  7. Completing the parallelogram: You now have points A, B, C, and D. Connect points A to B, B to D, and D to C using your ruler to complete the parallelogram ABCD.
  8. Verifying dimensions: Ensure that the opposite sides are equal (AB = CD and AD = BC) to ensure correctness. Also check if the angles between adjacent sides are 70 degrees.

This method ensures the parallelogram is constructed accurately based on the given dimensions and angle.
