The cards Question In a transformation, what is the object? Tap to flip Answer The starting figure before a transformation has been applied. Question In a transformation, what is the image? Tap to flip Answer The resulting figure after a transformation has been applied. Question What is a transformation? Tap to flip Answer A process that may change the size, orientation or position of a shape. Question When are two shapes congruent? Tap to flip Answer When one can fit exactly on top of the other using rotation, reflection or translation. Question When is a property of a shape invariant? Tap to flip Answer When it has not changed after the shape is transformed. Question Are two squares with different side lengths congruent? Tap to flip Answer No: congruent shapes must also be the same size. Question What is a translation? Tap to flip Answer A transformation in which every point of a shape moves the same distance in the same direction. Question After a translation, do the object and image have the same orientation? Tap to flip Answer Yes. Question How are 'translation' and 'transformation' related? Tap to flip Answer A translation is one type of transformation. Question What is displacement? Tap to flip Answer The distance from the starting point when measured in a straight line. Question What can be used to describe a translation? Tap to flip Answer A vector. Question When describing a translation, between which points should you count? Tap to flip Answer Corresponding vertices of the object and image. Question What is a vertex? Tap to flip Answer The point where two or more line segments meet (plural: vertices). Question Column vectors work in the same way as what? Tap to flip Answer Coordinates. Question What is a rotation? Tap to flip Answer Turning an object by a fixed amount around a fixed point. Question When does a rotated image have the same orientation as its object? Tap to flip Answer Only after a full rotation (360°). Question What is the clockwise direction? Tap to flip Answer The direction the hands of an analogue clock travel. Question How many degrees make one whole turn? Tap to flip Answer 360° Question In what unit is the size of a rotation given? Tap to flip Answer Degrees. Question What is the centre of rotation? Tap to flip Answer The fixed point about which an object is rotated. Question What three things fully describe a rotation? Tap to flip Answer Its centre, size and direction. Question Must the centre of rotation be in the centre of the object? Tap to flip Answer No: it can be on a vertex, inside or outside the object. Question What is a reflection of a shape? Tap to flip Answer Its mirror image, made by flipping the object over a fixed line. Question What is the sense of an object? Tap to flip Answer The direction of the orientation of the object. Question How are an object and its image positioned relative to the line of reflection? Tap to flip Answer They are equidistant from it. Question Give one direction a line of reflection can take. Tap to flip Answer e.g. vertical, horizontal or diagonal. Question After a reflection, can line segments joining corresponding points intersect? Tap to flip Answer No, they never intersect. Question What is an enlargement? Tap to flip Answer A transformation that causes a change of size. Question Does an enlargement always increase size? Tap to flip Answer No: it can be a stretch or a shrink. Question When are two shapes similar? Tap to flip Answer When the only difference between them is their size; their side lengths are in the same proportions. Question Do the angles inside an object change when it is enlarged? Tap to flip Answer No. Question What is a scale factor? Tap to flip Answer The multiplier between similar shapes describing how large one is compared to the other. Question What is the centre of enlargement? Tap to flip Answer The point from which a shape is enlarged. Question For a positive scale factor, do the object and enlarged image have the same orientation? Tap to flip Answer Yes. Question In an enlargement, what happens to each vertex's distance from the centre of enlargement? Tap to flip Answer It is multiplied by the scale factor. Question Which is the only transformation that changes the sense of an object? Tap to flip Answer A reflection. Question What is a polygon? Tap to flip Answer A flat (2D), closed figure made of straight line segments. Question Turning clockwise x degrees is equivalent to turning anticlockwise by how much? Tap to flip Answer (360 - x) degrees.

How this deck was checked On 2026-11-03, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
