Question

can someone please help me?

Answer 1

with..?

Answer 2

i will post the question give me a sec

Answer 3

Observe parallelogram ABCD plotted on the coordinate plane below.

Part I: Provide the coordinates of a parallelogram A’B’C’D’ that is congruent to parallelogram ABCD. Explain why these figures are congruent.

Part II: Provide the coordinates of a parallelogram A’’B’’C’’D’’ that is similar to parallelogram ABCD. Explain why these figures are similar.

Answer 4

so first thing, what have you tried so far?

Answer 5

i havent tried anything cause i dont really understand it.

Answer 6

ok, so congruent means equal to, gotta love mathematicians ;) so for part I all you need to do is pick any point on the plane, and then make a parallelogram that is the same one as shown there, just at a different spot on the graph. there are no specific coordinates of this equal parallelogram, all you are basically doing is drawing a replica anywhere. so for part ii similar basically means LARGER or SMALLER so do the same thing as part I but choose your four points so that they are a miniature of the given parralellogram

Answer 7

ok so can i choose some points and you tell me if i am correct?

Answer 8

ya. go for it.

Answer 9

do congruent first

Answer 10

it cant be the same size?

Answer 11

congruent is the same size. if A is congruent to B then you write, A = B . its just a fancy way of saying equal to. when to shapes are SIMILAR then they are not the same size. similar shapes are like when you compare a small ball and a big ball. exact same shape just different sizes

Answer 12

okay so 1,1 A.... 3,3 B..... 7,3 C..... 5,1 D?

Answer 13

is that good?

Answer 14

@matineesuxxx ?

Answer 15

sorry my comp was being weird. so if you do (1,1) you can't do (3,3). do you remember slope? rise/run?

Answer 16

ohh so ugh i dont know now

Answer 17

if you take the slope of points b and c on the drawing that you are given, you don't get the same slope as you do when you use your points (1,1) and (3,3)

Answer 18

im not sure what to do now

Answer 19

i have another one?

Answer 20

@matineesuxxx

Answer 21

im sorry this website keeps messing up on my computer

Answer 22

um, look on the picture you first showed me. look at point D. now go one space to the right, and 2 spaces up. you are back on the line. now when you draw YOUR parallelogram, the diagonal lines should be that way too. one space right, 2 spaces up

Answer 23

A(-5, -6), B(-3,-2), C(?,?) D(?,?)

Answer 24

my c & d was wrong?
