Answer:

  b, c

Step-by-step explanation:

Reflection across a line is a "rigid" transformation, so linear measures and angle measures remain unchanged. (b and c are true statements)

Reflection across a line skew to the y-axis will mean that any segment originally perpendicular to the y-axis will not be after the reflection. ('a' is not a true statement)
