PLEASE HELP!!!!!! 25PTS!!
Which statement explains why △ABC is congruent to △A′B′C′?
a)You can map △ABC onto △A′B′C′ by reflecting it over the y-axis and translating it 4 units down, which is a sequence of rigid motions.
b)You can map △ABC onto △A′B′C′ by reflecting it over the x-axis and translating it 7 units right, which is a sequence of rigid motions.
c) You can map △ABC onto △A′B′C′ by rotating it 90° clockwise about the origin and translating it 5 units right, which is a sequence of rigid motions.
d)You can map △ABC onto △A′B′C′ by reflecting it over line y = x and translating it 5 units right, which is a sequence of rigid motions.
