Triangle ABC is reflected across them-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 shape is reflected across the x-axis, the y-coordinates of the points are negated.
Therefore, the coordinates of A' would be (-4, -(-1)) which simplifies to (-4, 1).
The coordinates of B' would be (-5, -(-2)) which simplifies to (-5, 2).
The coordinates of C' would be (-10, -(-1)) which simplifies to (-10, 1).
In summary, the coordinates of A', B', and C' are (-4, 1), (-5, 2), and (-10, 1), respectively.
