To solve this worksheet students should have a good understanding of reflection and coordinate plane. If a point is reflecting over the x-axis then the reflection rule is (x,y)→(x,-y), and if a point is reflecting over the y-axis then the reflection rule is (x,y)→(-x,y). For example, if the vertices of a triangle are A(1,2), B(1,5) and C(4,3), and it is reflected over the x-axis, then the vertices of the new triangle are A(1,-2), B(1,-5) and C(4,-3).
