HURRY DO ALL QUESTIONS PAST DUE

I’m only doing 3 and id k if I’m right either so lol but A is a reflection I think and I don’t think B is congruent which mean some of the size and not like right like they don’t match or something like that and to be nice on number 5 trace the tree up the blue zigzag yea trace it rly hard fold it then rub on the back of the paper the shape should end up on the other side that’s how I cheated try doing that with number 4 too

Step-by-step explanation:I’m sry if that doesn’t make sense I tryed

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.
