b) Triangle ADF has been reduced by a scale factor of 3/5 to form triangle ABC.

c)Triangle ABC has been enlarged by a scale factor of 5/3 to fom triangle ADF

d) Triangle ABC has been reduced by a scale factor of 3/8 to form triangle ADF.

Answer 1

Draw the triangles on a coordinate graph first.

Answer 2

Do you know how to do that using draw feature below?
