Question

Help please !!!!!

Answer 1

Graph a triangle (XYZ) and reflect it over the line y=-x to create triangle X'Y'Z'.
Part 1: Describe the transformation using words.
Part 2: 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?
Part 3: 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 3

@Ashleyisakitty can you help me please?

Answer 4

@Rina.r

Answer 5

Triangle XYZ is located at X (-2, 1), Y (-4, -3), and Z (0, -2).

Answer 6

Sorry

Answer 7

@Hero @mathslover anyone please ??

Answer 8

I dont understand parts 2 and 3.

Answer 9

@ehuman

Answer 10

Anyone ....?

Answer 11

I graphed it and did part 1 now as i connect the point to the line of reflection i am confused

Answer 12

so pretend this is what you drew. and now you have to reflect this same thing on the other side..

Answer 13

so the black part is what you have to do

Answer 14

but make sure how ever many squares it is on one side, thats how it is on the other.

Answer 15

okay

Answer 16

wait but you had to reflect the triangle over y=x

Answer 17

then draw a segment from X to the line of reflection and X" to the line of reflection

Answer 18

right. so it would be this way...

Answer 19

and then copy it over on this side.

Answer 20

btw. this is just an example. these are not the right coordinates. but it is how you are supposed to reflect.

Answer 21

oh ok

Answer 22

I came up with this . Part 1
They both lie on the line of reflection. The triangles overlap each other . They y and x - coordinates were switched.
Part 2
Both segments end at the same point in the line of reflection.
Part 3
When reflecting an object over the line y=x the x and y intercepts are switched but still congruent so , the distance will be the same from the point to the line of reflection .
Is it correct?

Answer 23

yes :) well done! is that all you needed?

Answer 24

can you help me with one more question ?

Answer 25

thanks !:)

Answer 27

Determine if the two figures are congruent and explain your answer. If they are congruent, tell which rigid motions were used.

Answer 28

Can you please help if you can .

Answer 29

@Stormswan

Answer 30

well, they are congruent. the word congruent means the same. so if you look at the two figures, they look very much alike. It would be a glide reflection :)

Answer 31

would that be it?

Answer 32

i know they are congruent but i really dont know what a glide reflection is

Answer 33

My teacher wants us to be specific :)

Answer 34

If its reflection the line of reflection , translation , rule , rotation , angle

Answer 35

go here :) it has all of the rigid motions. https://www.math.ku.edu/~jmartin/courses/math105-F11/Lectures/chapter11-part3.pdf

Answer 36

And is it more than one motion

Answer 37

is the reflection on the y or x axis

Answer 38

y axis :)

Answer 39

Thank you so much !! I really appreciated your help ! :)

Answer 40

no problem :)

Answer 41

tag me if you need anything else.

Answer 42

Sure
