∆abc is reflected about the line y = -x to give ∆a'b'c with verticesa'(-1, 1), b'(-2, -1), c(-1,0). what are the vertices of ∆abc? options: a. a(1, -1), b(-1, -2). c(0, -1)b. a(-1, 1), b(1, 2), c(0, 1)c. a(-1,-1), b(-2, -1), c(-1,0)d. a(1, 1), b(2, -1), c(1,0)e. a(1, 2), b(-1, 1), c(0, 1)edit: it's b i figured it out
