Answer:
ΔCDE and ΔCGH
Step-by-step explanation:
Since the slope is 2/5 (or 0.4), then there can be drawn a function graph f(x)=0.4x whose slope is 2/5. So now let's draw a pair of parallel lines. We have then a pair of congruent triangles, i.e. ΔCDE ≅ ΔCGH. These triangles have their hypotenuses on the line whose slope is 2/5.
