Answer:
The coordinates of the image triangle will be:
Please also check the attached figure.
The green triangle represents the image triangle.
Explanation:
We know that when we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate reveres its sign.
Thus,
The rule of reflection of the point P(x, y) across the x-axis is:
P(x, y) → P'(x, -y)
In the attached figure, let the coordinates of the triangle are:
Using the rule of reflection across the x-axis:
P(x, y) → P'(x, -y)
Thus, the coordinates of the image triangle will be:
A(-3, 1) → A'(-3, -1)
B(-3, 3) → B'(-3, -3)
C(-1, 3) → C'(-1, -3)
Therefore, the coordinates of the image triangle will be:
