18 ! drag the expressions to order them from least to greatest with the least at the top. 7/8 5/8 -1/4 -3/8 -3/4

least to greatest, -3/4, -3/8, -1/4, 5/8, 7/8

hope this helps :)

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.
