As a project for geometry students are asked to make an enlarged copy of a 3 inch by 4 inch cartoon. They are asked to draw a 1/4 inch by 1/4 inch grid on the cartoon, then draw a 1 inch by 1 inch grid on a 12 inch by 16 inch poster board. They are to copy the smaller cartoon by duplicating the marks from each 1/4 inch square to its corresponding 1 inch square on the poster board. This is an example of which transformation?
Translation
Rotation
Reflection
Dilation
What transformation maps a small letter "d" to a capital letter "P" ?
