To graph : The reflection of
a
Explanation of Solution
Given information : The following information is given regarding the coordinates of the original triangle
Thus, the triangle is as follows
Graph : Hence, we sketch the reflection of triangle PQR over the x axis. We thus get
Thus, the coordinates for the new diagram are
Interpretation : Thus, we can see from the above diagram that for reflection over the x axis,
b
To graph : The reflection of triangle PQR over the y axis has to be plotted with coordinates
b
