What single transformación maps ABC onto ABC?

A.

rotation 90' clockwise about the origin

O

B.

rotation 90' counterclockwise about the origin

O

c. reflection across the x-axis

O

D. reflection across the line y = x

a reflection across y-axis then translation of 1 unit right and 2 units up.

a clockwise rotation of 180° about the origin then a translation of 1 unit right and 3 units up

a reflection across y-axis then translation of 1 unit right and 1 unit down

a reflection across y = x then a positive rotation of 270° about the origin

I think its 180

Step-by-step explanation:

I think because 90 + 90 = 180
