Question

a double reflection of a preimage across perpendicular lines produce the same result as a: (1 point) 270 - degree rotation. 180 - degree rotation. 90 - degree rotation. scaled dilation.

Explanation:

In geometry, when a pre - image is reflected across two perpendicular lines, the transformation is equivalent to a 180 - degree rotation. This is a well - known property of geometric transformations. A 270 - degree rotation and 90 - degree rotation are not equivalent to double reflection across perpendicular lines. Scaled dilation changes the size of the figure, which is different from reflection and rotation.

Answer:

180 - degree rotation.
