Question:

Draw the square READ with RE = 5.1 cm.

Solution:

To draw square READ with side RE = 5.1 cm:

  1. Draw a line segment: Use a ruler to draw a straight line segment of length 5.1 cm. Label one endpoint as R and the other as E.

  2. Construct perpendicular lines:

    • At point R, use a protractor or compass to construct a line perpendicular to RE.
    • At point E, use a protractor or compass to construct a line perpendicular to RE.

  3. Mark points A and D:

    • On the perpendicular line at R, measure 5.1 cm and mark the point as A.
    • On the perpendicular line at E, measure 5.1 cm and mark the point as D.

  4. Complete the square: Draw a line segment connecting points A and D. You now have a square READ with each side measuring 5.1 cm.
