Mathematics - Geometry - Congruence and Similarity - Similar figures and scale factor - Similar Figures and Scale Factor
6 steps: (1) SIMILAR figures: same shape, different size. All angles equal, all sides proportional. (2) SCALE FACTOR: the ratio of corresponding sides. If triangle A has side 6 and triangle B has corresponding side 9, SF=9/6=1.5. (3) All corresponding sides have the SAME ratio. (4) Similar triangle
