  1. Objective 9-9 Quiz • Use a graph of ∆WXY with vertices W(-3, 3), X(-2, 0), and Y(0,2). • Graph ∆WXY. How many lines of symmetry does ∆WXY have? • For questions 2 and 3, either give me the coordinates of each new point or draw the reflection at the proper points • Give the vertices of ∆W’X’Y’, the image of ∆WXY after a reflection over the x-axis. • Give the vertices of ∆W’’X’’Y’’, the image of ∆WXY after a reflection over the y-axis.
