Step-by-step explanation:

Dear Gentleman Scholar —

Recently, I nearly reduced a woman to tears when she gently proffered her hand to me at a work conference and I vigorously squeezed it and yanked her around like the Incredible Hulk shaking hands with Raggedy Ann. There was much metacarpal cracking and muted whimpering. Having (I thought) learned my lesson, later at the same event when another women extended her hand, I very gently held hers and then released. There were no injuries this time, but she glared at me as if I had just handed her a dead fish. How does a gentleman shake hands with a lady? Am I supposed to shake it, caress it, kiss it, just hold it for a moment? What gives?

Yours,

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.
