Given the vertices:
C(-2, 4), D(1, 5), and E(1, 2)
Let's identify the reflection of the figure across the x-axis.
After a reflection across the x-axis, we have the rule:
(x, y) ==> (x, -y)
Thus, we have:
C(-2, 4) ==> C'(-2, -4)
D(1, 5) ==> D'(1, -5)
E(1, 2) ==> E'(1, -2)
Therefore, after a reflection over the x-axis, we have:
C'(-2, -4), D'(1, -5), E'(1, -2)
ANSWER:
C'(-2, -4), D'(1, -5), E'(1, -2)
