Question:

Reflect polygon ABCD over the x-axis. Draw he new polygon and record its coordinates in the table below.

A B C D
original polygon (1,5) (7,6) (9,4) (6,2)

original polygon
reflected over the x-axis


Answer:

Open the following link to see a graph of the polygon with coordinates (1,5) (7,6) (9,4) (6,2).

A reflection across the x-axis means:

a. that the x values do not change
b. the y values are all multiplied by -1

These are your original coordinates:

(1,5) (7,6) (9,4) (6,2)

These are the coordinates reflected across the x-axis:

(1,-5) (7,-6) (9,-4) (6,-2)


Open the following link to see a graph of the original polygon and its reflection across the x-axis.
