Exploring Reflections
Create a polygon!
Part 1:
- Use the polygon tool:
to create a quadrilateral on the coordinate plane below.
- Select one of the vertices of your quadrilateral and show the name of it by selecting the text tool:
and select "name". Repeat this process for all of the vertices. *Note: make sure before you select something, you have clicked on the move tool: 
!! - Use the reflect about line tool:
by clicking first on the tool, then one of the vertices of the quadrilateral, and finally click on the x-axis. - Repeat step 3 for all of the vertices of your quadrilateral.
- Record the coordinate pair for the original quadrilateral and the image.

!! - Use the reflect about line tool:
by clicking first on the tool, then one of the vertices of the quadrilateral, and finally click on the y-axis. - Repeat step 3 for all of the vertices of your quadrilateral.
- Record the coordinate pair for the original quadrilateral and the image.
Questions:
- What do you notice happens with the coordinates of the points when you reflect the quadrilateral over the x-axis?
- What do you notice happens with the coordinates of the points when you reflect the quadrilateral over the y-axis?
