The vertices of triangle ABC are a(8,23) B(2,2) C(2,8). What are the coordinates of the vertices if the triangle is reflected across the x-axis?

Question

is it A(8,2) B(2, -2) C(2, -8)?

Answer 1

reflection across the x-axis takes (x,y) --> (x,-y)

So, if (8,23) is supposed to be (8,-2), then you are correct.

Answer 2
