Copy of Discovering Properties of Parallelograms (Scaffolded Discovery)

Author:ekruckenberg, Tim Brzezinski, Julian Ornelas
The applet below contains a quadrilateral that ALWAYS remains a parallelogram. The purpose of this applet is to help you understand many of the geometric properties a parallelogram has. Some of these properties are unique and only hold true for a parallelogram (and not just any quadrilateral). The questions you need to answer are displayed below this applet.
Use this applet to investigate the answers to the following questions.

Are opposite sides of a parallelogram congruent?

Select all that apply
  • A
  • B
Check my answer (3)

Are consecutive angles of a parallelogram (angles right next to each other) supplementary? 7) Find the sum of the measures of each pair of consecutive angles in the parallelogram. (A and D, D and C, etc.)

Select all that apply
  • A
  • B
Check my answer (3)

Do the diagonals of a parallelogram bisect each other? (Cut each other in half)

Select all that apply
  • A
  • B
Check my answer (3)

Are the diagonals of a parallelogram perpendicular?

Select all that apply
  • A
  • B
Check my answer (3)

Does a diagonal of a parallelogram bisect a pair of opposite angles?

Select all that apply
  • A
  • B
Check my answer (3)

Are the diagonals of a parallelogram congruent? (Is the full length of one diagonal equal to the full length of the other diagonal?)

Select all that apply
  • A
  • B
Check my answer (3)
