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
When a point is reflected across the x-axis, its y-coordinate changes sign and its x-coordinate remains the same.
For point A, the original coordinates are (-4, -1). After reflecting across the x-axis, the y-coordinate becomes positive, so the coordinates of A' are (-4, 1).
For point B, the original coordinates are (-5, -2). After reflecting across the x-axis, the y-coordinate becomes positive, so the coordinates of B' are (-5, 2).
For point C, the original coordinates are (-10, -1). After reflecting across the x-axis, the y-coordinate becomes positive, so the coordinates of C' are (-10, 1).
Therefore, the coordinates of A' are (-4, 1), the coordinates of B' are (-5, 2), and the coordinates of C' are (-10, 1).
