Triangle transformation showing a dilation from a smaller triangle to a larger one with a scale factor of 2.
A coordinate plane showing a triangle with vertices T', R', and S' in blue, and a smaller triangle with vertices T, R, and S in black. The point R' is labeled (4, 4), and R is labeled (2, 2), with a red arrow and "4 ÷ 2" indicating a scale factor of 2.
