Lesson Activity
Diagonals of Parallelograms
This activity will help you meet this educational goal:
You will investigate the relationship between the diagonals of a parallelogram.
Directions
Read the instructions for this self-checked activity. Submit your response to each question,
and check your answers. At the end of the activity, write a brief evaluation of your work.
Activity
Use GeoGebra to explore diagonals of a parallelogram. Open congruent parts of
parallelograms to complete each step. For help, watch these short videos on using
GeoGebra to measure and create points, lines and angles .

Part A
Draw diagonals and on parallelogram . Make a point where the diagonals
intersect, and label it E. Measure and record the lengths of the four line segments you just
created by selecting the endpoints of each segment.
Type the correct answer in each box. Use numerals instead of words. Do not round your
answers.

Part B
Move the vertices of the parallelogram around and notice how your measurements from part
A change. What conjecture can you make about the relationship between the diagonals of
parallelograms?
Answer:
one diagonal is the vector sum of two sides, and the other is the vector difference
Space used (includes formatting): 90 / 15000
The diagonals of parallelograms bisect each other.
