Welcome to Openstudy :)
I seiriously need help....are you good at geometry? Not trying to offend you or anything, just asking
Geometry was never my favorite subject.. but I can always try. I would start off by setting the two equations equal to each other
ok......gimme a sec...
would it be x = 7??
Yup, that's what x would be, now what you do is plug that back in to get the side lengths
the side lengths would be 6 right? Thats what I got.
by the way i have one more question after this...
Yup, and alright shoot.
Thats my last one.
you have to identify each of the segment's coordinates first
Ok....so d = -2, 6 q = -4, 4 b = -3, 2 and a = -1, 1 Then for the second one h = 3, 5 g = 5, 3 f = 4, 1 e = 2, 0 now what?
Don't leave me!
I am here. can you calculate the distance of each segments and see if anything matches from figure one (right side) and figure two (left side
What do you mean cauculate the distance?
do you know the distance formula?
if not, you can derive it from pythagorean theorem.
Ummm.... what? sorry but this is why I needed help I dont remember.
Wouldn't counting the spaces work?
like counting from point d to point a. you go one to the right and 5 down. If you do the same from point H to point E it works too.
of course that works, but you want to be able to show it mathematically right?
I guess so, but it just says determine if the figures are congruent and expalin how you did it.
I mean explain
the explanation would be by means of mathematical procedure - by calculating each segment's length or what we normally refer to as distance.
Ok so I just do that for one side and then the corresponding side?
Or all of them?
exactly. it's a long work, but you get to practice a lot by the end of it.
you want to be able to do it strategically. look at the possible longest sides of each figure. calculate their distances and see if it matches.
ok, wait juuuuust a minute
ok, i did it for line DA and Line HE and Line DA came out to be sqrt(26) and Line HE was sqrt(10) so they aren't congruent?
are you sure? show me your calculation
d = sqrt (( -1 - -2) ^2 + (1 - 6)^2) d = sqrt ((1)^2 + (-5)^2 d = 1 + 25 d = 26 That was line DA is that one right?
OHHHHHHHH! I feel so stupid....I see it now...so they are congruent that much I understand, but I cannot figure out what transformations took place for that shape to get there... help me with that and I'll leave you alone ;)
ambulance... and I didn't need a mirror:0
I thought refelction at first too, but it would have to be a combination of both translation and reflection since it isn't exactly a mirror image on the other side. it's touching the x axis whereas the other one isnt
the instruction was important for you to follow… that's how you will make the connection between the word I gave you and the shapes you were given.
I get your point but read my previous post
In Geometry, "Translation" simply means Moving ... ... without rotating, resizing or anything else, just moving. http://www.mathsisfun.com/geometry/translation.html you didn't read the contents of the first link I gave you - this http://www.mathsisfun.com/geometry/transformations.html
I did read it... but the reflection isn't and exact mirror image thats what i'm trying to say. If it was an exact mirror image, the only difference between the shapes would be the fact that the x coordinates would be the same numbers, just positive.
I'm not telling you you're wrong, I'm just voicing my opinion.
if you insist, Thanks a bunch!
the reflection line can be at any direction
Ok thanks:) You helped a lot:) God bless.
so you want to say it's a combination of reflection and transformation?
I mean translation
I did, but I've already submitted my assignment. Thanks again!
always trust your self and if it turns out wrong, then learn from it. that's what I do at least in math.
That's true...good words to live by:) Closing question.
