Answer:
<em>C) 180 degree rotation </em>
Step-by-step explanation:
While reflecting a point, with coordinates as (x, y), over x axis the new co-ordinates become (x, -y)
⇒(x, y) → (x, -y)
While reflecting a point, with coordinates as (x, y), over y axis the new co-ordinates become (-x, y)
⇒(x, y) → (-x, y)
So, when these two operations are combined, they the rule followed is,
⇒(x, y) → (-x, -y)
We also know that while rotating a point, with coordinates as (x, y), 180° the new co-ordinates become (-x, -y)
⇒(x, y) → (-x, -y)
Therefore, reflecting a point over x axis and then over y axis will yield the same result as rotating a point 180°.
