7.4 Geogebra Task

  • Construct a rhombus
  • Remember a rhombus is a parallelogram with four equal sides
  • Do NOT make the angles 90 degrees
  • HINT: perhaps the easiest way is to rotate a segment
  • If you use rotating a segment, keep in mind rotations occur counter-clockwise and you will want to use mutliples of 10 for your angles to avoid decimals
  • Be sure your construction remains a rhombus even when dragged.
  • LAST STEP: create the diagonals of your rhombus and measure their lengths and angles created at the vertices of the rhombus
  • Answer the two questions below

Question 1

Is there a relationship among the four angles created by the intersection of the diagonals?

Question 2

What do the diagonals do to the angles of the rhombus?
