Question

Part C

Now check your predictions. In GeoGebra, draw the lines of reflection y = x and y = -x. Then reflect quadrilateral ABCD about the x-axis, y-axls, y = x, and y = -x. Enter the coordinates of the vertices of quadrilateral A'B'CD' in the table. Paste a screen capture of your images below the table.

Answer 2

see attached

Explanation:

GeoGebra conveniently computes the point coordinates of the reflected points. In the attached, the reflections are done in the order listed in the table, so A' is reflected across x; A'₁ is reflected across y; A'₂ is reflected across y=x, and A'₃ is reflected across y=-x. The same notation is used for the other points. The values are listed in order, so you can copy them down the column in your table.
