Jujuberry we all love Jujuberry sing along. Hello, I am the Jujuberry tree. I am here to ask you if you want to join the jujuberry clan. Yes or yee?

What?

Step-by-step explanation:

y

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.
