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?

- Vocaloid

have you tried drawing it?

- anonymous

no, I'm confused on where to plot it

- Vocaloid

it doesn't matter, it just says to draw any triangle LMN

- anonymous

okay, do i just pick any numbers and use those?

- Vocaloid

yes

- anonymous

Okay, but what does this mean "Describe the transformation using words"

- Vocaloid

describe what happens to the triangle after you reflect it across y= x

- anonymous

So I must draw a graph and plot it out?

- anonymous

@hartnn Help!

- Vocaloid

yes.

- Vocaloid

pick three points, draw a triangle

- anonymous

Okay

- anonymous

L = (1, 3)
M = (1, 1)
N = (4, 2)
I picked those

- Vocaloid

good, now plot them on a graph

- anonymous

Alright

- anonymous

now what

- Vocaloid

reflect the points across the line y = x

- anonymous

okay I think i'm understanding it

- Vocaloid

hint:
to reflect the point (x,y) across the y-axis, switch the x and y-coordinates
example: (5,4) becomes (4,5)

- Vocaloid

so, if L = (1,3), L' = ?

- anonymous

would there be any negitives?
(3.1)

- Vocaloid

nope, that's right

- anonymous

And do that will all three of them?

- Vocaloid

so L' is (3,1). draw this point and label it L' (don't forget the dash)

- Vocaloid

yes, do all three

- anonymous

Which part of the graph would it go on? l

- anonymous

Would it stay in the same square?

- Vocaloid

yes

- anonymous

Oh alright

- Vocaloid

@Nnesha need to run for a bit

- anonymous

they would over lap?

- anonymous

I plotted it and they over lap, is that okay?

Would you mind attaching the graph were you plotted?

- Koikkara

**where you plotted ?

- anonymous

I drew it on paper. I'm new to open study and don't know how to draw it on here.

@scary_bunny76 well, try this link: http://openstudy.com/study#/updates/548f3e4ee4b04ed7d6b5ae1b
Hope it helps.

draw points on this graph

- Nnesha

|dw:1443987691832:dw|
that's LMN now draw point L'M'N' just like voc told u to do it
reflect across y =x
