Transformations | Edexcel GCSE Foundation | 40 Worked Examples

Every question fully worked, one step at a time, in the Edexcel Foundation style. This 40-question pack builds transformations from the ground up across all four types on the Foundation tier: translations described as column vectors, reflections in the axes and in the lines x = a, y = b and y = x, rotations by 90 and 180 degrees about the origin and about other points, and enlargements with positive and fractional scale factors. Students learn to translate and reflect single points, apply the standard coordinate rules, describe a transformation fully from a diagram, draw enlargements from a centre, find a missing scale factor and centre by drawing rays, and tell congruent images from similar ones. On-grid coordinate diagrams are included throughout so the geometry is easy to follow. The challenging section stretches to enlargements about a centre that is not the origin, fractional enlargements, finding a centre from two shapes, and area and perimeter scale factors. It also drills the two rules that quietly lose marks: give one single transformation only when a question says describe fully, and give every detail (a rotation needs a centre). Negative scale factors and combinations of transformations are Higher-tier only and are left out on purpose. Each solution is broken down to one operation per line, with a plain-English note on every line and the real Edexcel mark-scheme codes [M1] [A1] [B1] [C1] folded in exactly where the marks fall. Clean, printable and mapped to spec references G8 and G24. Ideal for classwork, homework, revision or 1-1 tuition. Full answers included.
