Remember that with these constructions you can move the points around. You may create any triangle first, THEN reflect it with the checkboxes at the top left. Consider the following:
1) Does each reflection show up where you expect it to?
2) Can you identify the reflection rule BEFORE you click the last check box?
3) Will you be able to perform these tasks on your own (without GeoGebra)?
