Question

Polygons LMNO and L'M'N'O' are shown on the following coordinate grid:A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A polygon LMNO is shown with vertex L on ordered pair 2, negative 2, vertex M on ordered pair 4, negative 2, vertex N on ordered pair 1, negative 3 and vertex O on ordered pair 5, negative 3. A polygon L prime, M prime N prime O prime with vertex L prime on ordered pair negative 3, negative 2, M prime on negative 3, negative 4, N prime on negative 4, negative 1 and O prime on negative 4, negative 5.

Answer 1

Polygons LMNO and L'M'N'O' are shown on the following coordinate grid:A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A polygon LMNO is shown with vertex L on ordered pair 2, negative 2, vertex M on ordered pair 4, negative 2, vertex N on ordered pair 1, negative 3 and vertex O on ordered pair 5, negative 3. A polygon L prime, M prime N prime O prime with vertex L prime on ordered pair negative 3, negative 2, M prime on negative 3, negative 4, N prime on negative 4, negative 1 and O prime on negative 4, negative 5.

What set of transformations is performed on LMNO to form L'M'N'O'?

A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin

Answer 3

I was asking you to create a new question. Please do that next time.
I see your screen shot, but do not see any instructions for this problem.

Answer 4

i did create a new question

Answer 5

Separate from your first post, I meant.
But go ahead, share the instructions for your new question.

Answer 6

this is a new post

Answer 7

the question is above the screenshot

Answer 8

all right. My bad.
What have you done so far? What do you need to know?

Answer 9

i think its a

Answer 10

but idk

Answer 11

I want for you to understand how to do this and similar future problems on your own, so will not be responding to "I think it's a." Want to know how you chose one of the four possible answers and eliminated the others.

Answer 12

but i don't get itt

Answer 13

In that case it's best NOT to type something like "I think it's a."
Instead, try to find something (even if it's only a little detail) that you do understand. Then ask yourself what the next step would be.

You are beginning with trapezoid LMNO and must translate this figure in 2 ways or more so that you end up with trapezoid L'M'N'O' Have you gone thru all four possible answers to eliminate any that could not be correct?

Answer 14

i dont know

Answer 15

What does "90 degree counterclockwise rotation about the origin" mean to you?

Are you familiar with quadrants: e. g., Quadrant I, Q II, Q III, Q IV?

Answer 16

no

Answer 17

What does "90 degree counterclockwise rotation about the origin" mean to you?

Answer 18

i think its a 270 rotation

Answer 19

it rotates 90 degrees to the left

Answer 20

You'd need to include the info that you're drawing a straight line from the origin to point O and then rotating this line 90 degrees counterclockwise. You'd then need to do the same for points L, M and N. Question: Would the resulting trapezoid look like trapezoid L'M'N'O'? yes or no?

Answer 21

no?

Answer 22

Would the resulting trap. be in the lower left quarter of the coordinate grid? (We'd call that Quadrant III.)

Answer 23

no

Answer 24

OK. Eliminate the first answer choice.
Then repeat this procedure for the 2nd answer choice.

Answer 25

umm

Answer 26

"A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left." Know how to construct a "270 degree cc rotation about the origin?"

Answer 27

Draw a line from the origin to point L and then rotate that line counterclockwise 270 degrees. Repeat for points M, N and O.

Answer 28

i don't knoww how to do this

Answer 29

Connect the four new points. Does the resulting trapezoid look like trapez. L'M'N'O' ?

Answer 30

ya

Answer 31

To bad we can't do this problem on a blackboard.
However, it appeared that you understood what "a 90-degree counter clockwise rotation" meant. Only difference here is that the angle is now 270 degrees, not 90degrees.

Answer 32

ya ok

Answer 33

Try it, please.

Answer 34

i can't because i don't know how so thanks for your help but ill just guess

Answer 35

I understand that this is a new situation for you. It just might help you if you were to ask questions instead of saying "I don't know how."

All right, you're welcome. Sorry we haven't brought this problem to a conclusion.
