The pairs of polygons below are similar. The scale factor of figure A to figure B is 4.
Given two polygons A and B such that A ≈ B
If the ratios of the corresponding sides and angles of two polygons are the same, then the polygons are comparable.
The scale factor is the variable that indicates how much the provided figure grows or reduces in size.
Suppose we have a equation y = kx then kis a scale factor.
Let figure A be LMNO and figure B be PQRS such that
OL = 2
LM-4
PQ = 8
QR = 16
In LMNO and PQRS
OL / PQ = 2 / 8
OL / PQ = 1 / 4
PQ = 4OL
and
LM / QR = 4 / 16
LM /QR = 1 / 4
QR = 4LM
Comparing these two equation with y = kx, k = 4 (where k is scale factor)
