B. Triangle KLM is rotated 90 degrees clockwise about point L and then translated 4 units down.
C. Triangle KLM is rotated 90 degrees counter-clockwise about point L and then reflected across the x-axis.

Answer 1

D is correct,

Answer 2

Triangle J is congruent to triangle J′.
Which is a possible sequence of transformations that could take triangle J to triangle J′?
A. reflection across the y-axis and translation 4 units up
B. rotation 90 degrees clockwise and then reflection across the x-axis
C. reflection across the x-axis and then translated 4 units left
D. reflection across the x-axis and then reflection across the y-axis <---

Answer 3

D is correct, if you follow the very tip of the triangle, Its 2 points away from the x axis. if you count down 2 from the x axis that lines up with the other tip. then if you count the distance towards y axis (4) and it is also 4 on the other side then you have perfect reflections.

Thanks! :):):)
