Find the correct plugged in formula for each figure.

I would answer but I don't know it

Step-by-step explanation:

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.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
