Question

A double reflection of a pre-image across perpendicular lines produce the same result, as
1:scaled dilation
180 rotation
90-degree rotation
270-degree rotation

Answer 1

This statement is incorrect. A double reflection of a pre-image across perpendicular lines does not always produce the same result as the other transformation options mentioned (scaled dilation and rotations).

A double reflection across perpendicular lines results in a 180-degree rotation about the point of intersection of the two lines. This is different from a scaled dilation, 90-degree rotation, or 270-degree rotation, which would produce different images.
