Question

Triangle OWL was rotated to create triangle O'W'L'. Describe the transformation using details and degrees.

Triangles OWL and O prime, W prime, L prime are shown. O is at 1, 2. W is at 3, 1. L is at 2, negative 2. O prime is at negative 2, 1. W prime is at negative 1, 3. L prime is at 2, 2.

Answer 1

Please someone answer this correctly for me and i will give you ALL my medals.

Answer 4

So the points are `O(1,2) , W (3,1), L(2,-2)` and then `O'(-2,1), W' (-1,3), L'(2,2)` right?

Answer 5

Oh ok :) I understand.

Answer 6

Lets analyze the points...

We see that we start with `O(1,2) and end up with O'(-2,1)` Well the x and y values seem to switch places and makes the y-value be a negative....lets see if this occurs with the second one :)

`W(3,1) to W'(-1,3)` Does the same occur to this one?

Answer 7

Try refreshing the page :)

Answer 8

i think it does with that one swell

Answer 9

aswell

Answer 10

it lets me right now lol yay

Answer 11

Correct :) So since the values seem to switch places this would only mean it is a rotatation....lets write out the rule first....

\(\huge\bf{(x,y) \rightarrow (-y,x)}\)

This the rule for our transformation....

~~~~~~

Now since the points change places that would only mean that it can be a 90 degree clockwise or counterclockwise rotation because a 180 degree rotation would only have the values as a negative...Lets write the rule for `90 degree clockwise and counterclockwise rotation` And choose which one of ours follows...

90 degree counterclockwise:
\(\huge\bf{(x,y) \rightarrow (-y,x)}\)

90 degree clockwise:
\(\huge\bf{(x,y) \rightarrow (y,-x)}\)

Which one does it follow?

Answer 12

i think the 90 degree clockwise?

Answer 13

@563blackghost ^ sorry lost connection

Answer 14

I'm thinking counterclockwise but I'm to sure

Answer 15

not*

Answer 16

Yes its counterclockwise :)

Answer 17

oh good lol

Answer 18

^.^ and its find your intern disconnected mines not good today as well.

Answer 19

is that the end of the question?
