Enlargements Flashcards

A type of transformation that changes the size of a shape but not its shape.

The number by which each side of a shape is multiplied during an enlargement.

The fixed point from which distances are measured in an enlargement.

An enlargement where the shape is scaled up or down but remains on the same side of the centre of enlargement.

An enlargement where the shape is reflected and scaled on the opposite side of the centre of enlargement.

The shape becomes larger in size during the enlargement.

The shape becomes smaller in size during the enlargement.

A point that does not move during a transformation, such as the centre of enlargement in an enlargement.

Draw lines through corresponding points of the original and enlarged shapes. The point where the lines meet is the centre of enlargement.

The shape remains similar to the original, angles stay the same, and side lengths are proportional to the scale factor.
