Question

I really need help please

Graph a triangle (LMN) and reflect it over the line y=x to create triangle L'M'N'. Describe the transformation using words. Draw a line segment from point L to the reflecting line, and then draw a line segment from point L' to the reflecting line. What do you notice about the two line segments you drew? Do you think you would see the same characteristic if you drew the line segment connecting M with the reflecting line and then M' with the reflecting line? How do you know?

Answer 1

Is this on a 3d plane or 2d?

Answer 2

What do you mean?

Answer 3

Lol, not very well represented. If she hasn't learned about them yet, it's probably 2D.

Answer 4

This is very confusing.

Answer 5

interchange the coordinates i.e,x with y and viceverse.

Answer 6

So basically you combine the two parts?

Answer 7

I just dont understand this.

Answer 8

Have you graphed a random triangle on a coordinate plane yet?

Answer 9

Yeah kinda.

Answer 10

Think you can show us so we have an idea?

Answer 11

I have most of the answer
I just dont understand part 3

Answer 12

Which part does that ask for? (Just wanna be sure)

Answer 13

Heres what I have already

Part 1: The coordinates for LMN are:
L = (1, 3)
M = (1, 1)
N = (4, 2)
The points for the reflected triangle L'M'N' are:
L' = (3, 1)
M' = (1, 1)
N' = (2, 4)
Part 2:
The lines are connecting and are straight because it was flipped at a 180* angle.
Part 3:

Answer 14

This is literally so confusing I think I just give up

Answer 15

Nah, don't give up. Let me jot down a picture and we'll go from there, gimmie a second

Answer 16

Do you think you would see the same characteristic if you drew the line segment connecting M with the reflecting line and then M' with the reflecting line? How do you know?

^ This part is what we need to answer, right?
