How to Do a Reflection in GeoGebra

You can use GeoGebra to reflect a figure, just like you would with a compass.

GeoGebra Instruction 1

1.
Open Algebra View and Graphics View under GeoGebra icon View in GeoGebra icon Menu.
2.
Draw the figure you want to reflect, and the line of symmetry about which the reflection will occur. If you need instructions on how to do this, you can read GeoGebra Instruction 3 in this entry.
3.
Select the Reflect about Line GeoGebra icon tool. Click the figure, then the line. Your figure has just been reflected!
