2 3 24 8 3 1 Part A Is this a proportional relationship? yes Part B If this is a proportional relationship, what is the constant? Write N/A if it is not proportional. Part C If this is a proportional relationship, write a direct proportion equation. Write N/A if it is not proportional.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
