Question 4 • GRADY 24-25 VA-Geometry

Jaipal drew a triangle that had coordinates (1, –2), (4, –2), and (1, –4). He reflected the figure across the x axis. What are the coordinates of the new figure?

Answer
A
(–1, –2), (–4, –2), and (–1, –4)
B
(–1, 2), (–4, 2), and (–1, 4)
C
(1, 2), (4, 2), and (1, 4)
D
(2, –1), (2, –4), and (4, –1)

Explanation

Reflecting a point across the x-axis keeps its x-coordinate the same and changes the sign of its y-coordinate: (x, y) becomes (x, −y). Thus (1, −2), (4, −2), and (1, −4) become (1, 2), (4, 2), and (1, 4). Choice C gives these coordinates.
