Help please !!!!!
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?
@Ashleyisakitty can you help me please?
Triangle XYZ is located at X (-2, 1), Y (-4, -3), and Z (0, -2).
@Hero @mathslover anyone please ??
I dont understand parts 2 and 3.
I graphed it and did part 1 now as i connect the point to the line of reflection i am confused
|dw:1387784356740:dw| so pretend this is what you drew. and now you have to reflect this same thing on the other side..
|dw:1387784491971:dw| so the black part is what you have to do
but make sure how ever many squares it is on one side, thats how it is on the other.
wait but you had to reflect the triangle over y=x
then draw a segment from X to the line of reflection and X" to the line of reflection
|dw:1387784703117:dw| right. so it would be this way...
|dw:1387784771136:dw| and then copy it over on this side.
btw. this is just an example. these are not the right coordinates. but it is how you are supposed to reflect.
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?
yes :) well done! is that all you needed?
can you help me with one more question ?
Determine if the two figures are congruent and explain your answer. If they are congruent, tell which rigid motions were used.
Can you please help if you can .
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 :)
would that be it?
i know they are congruent but i really dont know what a glide reflection is
My teacher wants us to be specific :)
If its reflection the line of reflection , translation , rule , rotation , angle
go here :) it has all of the rigid motions. https://www.math.ku.edu/~jmartin/courses/math105-F11/Lectures/chapter11-part3.pdf
And is it more than one motion
is the reflection on the y or x axis
y axis :)
Thank you so much !! I really appreciated your help ! :)
no problem :)
