To solve this worksheet, students should have a deep understanding of coordinate plans and translation. For example, if the vertices of a triangle are A(4,3), B(4,7) and C(8,4), and the triangle is shifted 3 units left and 2 units down, then the rule of translation is (x,y)→(x-3,y-2). Using this rule to coordinates of the new triangle are A’(1,1), B’(1,5), and C’(5,2).
