Question

Graph a triangle (XYZ) and reflect it over the line y=x to create triangle X'Y'Z'. Describe the transformation using words. Draw a line segment from point X to the reflecting line, and then draw a line segment from point X' 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 Y with the reflecting line and then Y' with the reflecting line? How do you know?

Answer 1

This might help explain things, but it will not give you an direct answer: http://www.mathsisfun.com/geometry/transformations.html Try the problem after reviewing this website.

Answer 2

@e.mccormick can you help

Answer 3

Answer 4

There seems to be missing info

Answer 5

that is the whole question

Answer 6

so they want you to make up coordinates for X,Y, and Z?

Answer 7

review your flvs lessons, maybe it will help

Answer 8

I have done that already

Answer 9

ok pick a random point that doesn't lie on the line y = x

what point did you pick?

Answer 10

3,2

Answer 11

what do you get if you reflected that over the line y = x ?

Answer 12

Try graphing it on graph paper

Answer 13

would it be 1,3

Answer 14

close

Answer 15

reflecting (x,y) over y = x gives you (y,x)

Answer 16

2,3

Answer 17

(3,2) --> (2,3), yep

Answer 18

can you help me form an explanation?

Answer 19

plot those two points and the line y = x

Answer 20

then connect those two points with a segment. What do you notice about the line y = x and the segment?

Answer 21

idk

Answer 22

did you plot those things on the coordinate grid?

Answer 23

yes

Answer 24

can you see how the segment is perpendicular to the line?

Answer 25

and how the line cuts the segment in half?

Answer 26

no
