Which triangle would be congruent to the original using a reflection over the x-axis and the y-axis?
a)
b)
c)
d)

Option D.

Step-by-step explanation:

A triangle when reflected over x-axis option C is the reflection with a new base of the triangle is at y = -1 and the original picture is rotated 180° over x axis.

Further triangle in option C is reflected through y-axis or rotated at 180° by y axis then the new image will be as option D which is congruent to the triangle in original figure.

Therefore Option D is the correct answer.
