MISSING SIDES (1)
Step 1. Determine the Missing Labels
Examine the five polygons on the GeoGebra page.
The length label is missing on some sides (A-F).
Use what you know about perimeter to figure out the length of the missing side. Do not turn on the GRID, but use reasoning.
Fill in the Length of Missing Sides (in units) column.

Step 2. Check Your Answers
Use the DISTANCE OR LENGTH tool to click on each missing side and label it with the actual length.
In the Results Table, pick “ok” in the Check column if your answer for the length was correct.
If your answer was not correct, write the correct length in the Check column.
Step 3. Print
After you have labeled all the missing lengths using the DISTANCE OR LENGTH tool, print the GeoGebra page.
