wut exactly do you need help with brother?
So
I missed that while i was sick
I just
Need to know
How to do it
Oh i deleted name
Draw a rectangular parallelepiped ABCDA1B1C1D1. Specify the plane that is perpendicular to the line DD1
oh,

parallelopiped is a 3D parallelogram, if im not wrong
Ig so, English is my second language
yeah. you just draw a 3d parallelogram
So ye
just like you would draw a cuboid
Wait
It traduced bad
It should be
Draw a paralelogram ABCDA1B1C1D1. Specify the plane that is perpendicular to the line DD1
Or parallelopied
So ye
Main thing
What plane is perpendicular to DD1
And how to get it
in your figure, how many faces does this parallelopiped have?
What is face
So
Ye
6
Well, if I understood so ye
a plane is anything 2D
so, each side would be a plane
and each edge, a line
now, which planes here seem perpendicular to the line DD1?
Umm
AB1C?
Or ABC
you form a plane using 4 vertices
using 3 vertices makes it look like you are referring to the angle
But in possible answers only answers is maced from 3
thats really weird
The language barrier between me and you☠️
Накресліть прямокутний паралелепіпед ABCDA1B1C1D1. Вкажіть площину, яка перпендикулярна до прямої DD1
Idk anything from that, but i need to do that homework untill next 3 hours
Theres 7 more questions

💀
gl with that though
hmm, about this question
if you consider 3 points
so, which planes will be perpendicular to DD1?
ADD1
DD1 is ON the plane ADD1, so it cannot be perpendicular to it really
Wait
I don’t understand that question
the line DD1 should pass through the plane such that it makes 90 degree with the plane.
that is wut it means when a line is perpendicular to a plane
yeah!
Yes?
yes
ABC is the base plane. correct?
ye
OH WAIT
so the plane ABCD is perpendicular to DD1
which also means the plane ABC
if you include 3 vertices only
yee
correct
oh, i'm bout to go sleep rn lol
