Which of these triangle pairs can be mapped to each other using two reflections?

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)
