Triangle ABC is reflected across the x -axis. If the coordinates of the original shape are A(−4,−1) , B(−5,−2) , and C(−10,−1) , what are the coordinates of A′ , B′ , and C′ ?
To reflect a point across the x-axis, the x-coordinate remains the same and the y-coordinate is negated.
The original coordinates are:
A(-4, -1)
B(-5, -2)
C(-10, -1)
After reflecting across the x-axis, the coordinates become:
A'(-4, 1)
B'(-5, 2)
C'(-10, 1)
