Final answer:
In similar triangles, corresponding sides are proportional. So, if triangle HCS ~ triangle PLD, then the ratio HC/HS is equal to the ratio of the corresponding sides of triangle PLD.
Step-by-step explanation:
In similar triangles, corresponding sides are proportional. So, if triangle HCS ~ triangle PLD, then we have the proportion:
HC/HS = PL/PD
Since we don't have the specific values of HC, HS, PL, and PD, we can't find their ratio without further information.
