1) Plot the points ([b]type[/b] the ordered pair into the [b]input bar[/b], bottom of the page)[br][b]2) A(5,-1), B (3,-1) and C (4, -3)[br][/b][br]3)[icon]https://www.geogebra.org/images/ggb/toolbar/mode_polygon.png[/icon]Use the polygon tool to construct the triangle ABC[br][b]4) [icon]https://www.geogebra.org/images/ggb/toolbar/mode_mirroratline.png[/icon][/b]Use the reflection tool (9th tool over, under the reflection diagram)[br]5) Select the [b]Triangle ABC, then x-axis[/b]
List the points of A"B" and C"
If a Triangle is in quadrant 2, and we reflect it over the [b]x_axis [/b]which quadrant would the image be in?
