Question

The vertices of △ABC are located at A(−2,6), B(0,4), and C(2,6). △ABC is reflected over a line such that the resulting image has vertices at A′(2,6), B′(0,4), and C′(−2,6). The vertices of △DEF are located at D(−2,6), E(−2,2), and F(2,6). What will be the coordinates of the image of △DEF after a reflection over that same line?

Answer 1

Answer:

D'(2,6), E'(2,-2), and F'(-2,6)

Step-by-step explanation:

The vertices of △ABC are located at A(−2,6), B(0,4), and C(2,6)

△ABC is reflected over a line

resulting image has vertices at A′(2,6), B′(0,4), and C′(−2,6).

no change in  y

 change  x as -x   so reflected over the y axis

The vertices of △DEF are located at D(−2,6), E(−2,2), and F(2,6).)

The coordinates of the image of △DEF after a reflection over that same line

is D'(2,6), E'(2,-2), and F'(-2,6)
