the vertices of a triangle are a (-2,-5) b(-2,6) c (9,-5)the vertices of triangle a'b'c'obtained by dilating triangle abc are a( -8,-20 ) b(--8,24) c(36,-20) what is the scale factor
All the numbers are multiplied by 4 so the scale factor is 4 new:1old The scale factor is 4.
The centre of the dilation is the origin. [ also, I assume you meant B' to be (-8,24) ]
