which set of transformations would prove δlmn ~ δpqr?

dilate δpqr by the scale factor of 2 from point r, and translate δp′q′r′ by the rule (x + 0, y − 1).
dilate δpqr by the scale factor of 2 from point q, and translate δp′q′r′ by the rule (x + 1, y + 0).
translate δpqr by the rule (x + 1, y + 1), and dilate δp′q′r′ by a scale factor of 2 from point p.
translate δpqr by the rule (x + 1, y − 1), and dilate δp′q′r′ by a scale factor of 2 from point r.
