Triangle ABC will be dilated according to the rule(x,y), where point F is the center of dilation.

Rectangle ABCD was dilated to create rectangle A'B'C'D' using point R as the center of dilation.

What is the location of point G, which partitions the directed line segment from D to F into a 5:4 ratio?

Triangle QRS is to be dilated using the rule .

Triangle A B C is cut by line segment M N. Line segment M N goes from side A B to side B C and cuts both sides into equal parts. The lengths of A M and M B are 88 centimeters, the lengths of C N and N B are 75 centimeters, and the length of A C is 116 centimeters.

Point O is the center of dilation. Triangle D E F is dilated to create smaller triangle D prime E prime F prime. The length of O F prime is 3. The length of F prime F is 7.
