Points X and Y are in plane Z. Any point collinear with X and Y is also in plane Z pls need answer huhu =(
​

Yes, it's true that Any point that is collinear to points X and Y also lies in the same Z plane among X and Y.

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.
