Sample Flashcards

Scale Factor > 1

Shape gets BIGGER. SF = 2 means all lengths doubled. Only transformation that changes size!

Scale Factor < 1

Shape gets SMALLER. SF = 0.5 means all lengths halved. Still called "enlargement" even though it shrinks!

Sample Questions

Which of the following statements correctly describes an enlargement?

A. A transformation that changes the shape of an object but keeps its size the same
B. A transformation that changes the size of a shape using a scale factor and a centre of enlargement
C. A transformation that always makes a shape bigger
D. A transformation that rotates a shape around a fixed point
