A skate park is painting a simple logo on a rectangular sign. The logo is made from a single polygon with vertices joined in order: \(A(1,1)\), \(B(7,1)\), \(C(7,3)\), \(D(4,6)\), \(E(1,3)\), then back to \(A\).
The sign painter wants to use transformations to create a matching version of the same logo on the right-hand side of the sign.
The painter reflects the polygon across the dashed line \(x=5\) to place a matching logo on the right side of the sign. Find the coordinates of the reflected point \(D'\) and explain how you worked it out.

In Unit 1 students will develop their numeracy practices to make sense of their personal, public and vocational lives. They will develop mathematical skills with consideration of their local, community, national and global environments and contexts, and an awareness and use of appropriate technologies. These units provide students with the fundamental mathematical knowledge, skills, understandings and dispositions to solve problems in real contexts for a range of workplace, personal, further learning and community settings relevant to contemporary society.
In this area of study students will learn to recognise, describe and name common two- and three-dimensional shapes. They will classify, manipulate, represent and construct common and familiar shapes in diagrammatical and concrete forms. They will also become familiar with common characteristics and properties used in classifying shapes.
