Question

when a figure undergoes a reflection, it changes (1 point) both position and size. both position and orientation. size only orientation only

Explanation:

A reflection in geometry is a transformation that flips a figure over a line (the line of reflection). This transformation changes the orientation of the figure (since it's a mirror - image flip) and can also change its position relative to the original figure. However, the size of the figure remains unchanged because reflection is a rigid transformation (it preserves the side lengths and angle measures, hence the size). So when a figure undergoes a reflection, it changes both its position (as it's flipped over the line of reflection, so its location relative to the original is different) and its orientation (it's a mirror - image, so the orientation is reversed).

Answer:

both position and orientation
