To determine which pair of triangles can be used to show that the slope of line \( a \) is the same anywhere along the line, we would typically look for triangles that share a common angle or have proportional sides.
Unfortunately, without the images or additional context describing each of the triangles (A, B, C, D), I cannot provide a definitive answer.
In general, though, when you find similar triangles along a straight line, they will show that the relationship of the vertical change (rise) to the horizontal change (run) — which defines slope — remains constant, regardless of where you measure it on the line.
If you have the images available, please describe them or provide more context so I can assist further!
