Need help with a stain glass assignment.

OpenStudy (anonymous):

OpenStudy (anonymous):

I'm going to post my 24 lengths for each of the polygons. And I just need to know if I add anything or erased and fix something. Okay? :o That is all I need to know then we can proceed on to the part 2!! :DDDDD

Directrix (directrix):

Post you lengths and the work if you have to show work to that teacher. I'm ready.

OpenStudy (anonymous):

I used the online calculator. But once I figure out everything is good, then I will show my work.

OpenStudy (anonymous):

Directrix (directrix):

Some of these look "off" to me.

Directrix (directrix):

Let's look at the triangle.

OpenStudy (anonymous):

Which ones?

OpenStudy (anonymous):

Okay. What's wrong with the triangle?

Directrix (directrix):

One out of three ain't bad, as they say.

Directrix (directrix):

You should be doing for the stomach: (0,4) to (3,0) (3,0) to (-3,0) (-3,0) to (0,4)

OpenStudy (anonymous):

So the answers I got needs to be erased and replace with those coordinates?

Directrix (directrix):

They are the wrong coordinates so I would replace them. I don't know where they came from unless it was difficult to read my writing.

Directrix (directrix):

Look at the stomach coordinates I just posted and see if you agree that they go with the drawing of the cat.

OpenStudy (anonymous):

I think that was the problem. Lol. But thank you for telling me the correct coordinates. I will find the length using the online calculator.

OpenStudy (anonymous):

Where are the coordinates for the stomach that you just posted? or do mean in the photo?

Directrix (directrix):

Find them now because we cannot let this first half of the project drag any longer. It's already Halloween where I live.

OpenStudy (anonymous):

Okay. I will.

OpenStudy (anonymous):

Could you please send me that online calculator from before?

Directrix (directrix):

Let me see you stomach lengths. Mine are ready.

Directrix (directrix):

(0,4) to (3,0) is __________ (3,0) to (-3,0) is ___________ (-3,0) to (0,4) is ____________

Directrix (directrix):

....waiting

OpenStudy (anonymous):

5?

OpenStudy (anonymous):

I'm sorry it took me forever.

Directrix (directrix):

(0,4) to (3,0) is ____5______ Yes. And, then ... (3,0) to (-3,0) is ___________ (-3,0) to (0,4) is ____________

OpenStudy (anonymous):

5 is for the first set I got 6 for the second set and for the third I got 5. correct?

Directrix (directrix):

Correct. Now, let me see where we should go next on these coordiniates.

OpenStudy (anonymous):

Okay. I will fix the coordinates on the picture.

Directrix (directrix):

Okay, I need to check the coordinates on the pentagonal cat head.

Directrix (directrix):

Head Coordinates

Directrix (directrix):

Distances Needed: E to F (0,4) to (2,6) = F to G (2,6) to (2,8) = G to H (2,8) to (0,10) = H to I (0,10) to (-2,8) = I to J (-2,8) to (-2,6) = J to E (-2,6) to (0,4) =

Directrix (directrix):

That is why the coordinates are off. The cat head is a hexagon, not a pentagon.

OpenStudy (anonymous):

EF, square root of 8, FG, 14, GH, square root of 8, HI, square root of 18, I J, 2, JE, square root of 8. Right?

Directrix (directrix):

EF, square root of 8 = 2√2; Yes FG, 14 NO Try Again ---> GH, square root of 8 Yes =2√2 , HI, square root of 18 NO---> Try Again , I J, 2, Yes JE, square root of 8 = 2√2 Yes

Directrix (directrix):

Two to do again. Hey, use the tab button to jump among those coordinate boxes on that site

Directrix (directrix):

Which part of the cat is the rhombus?

Directrix (directrix):

What you are calling a rhombus is a trapezoid. Those are the ears of the cat.

Directrix (directrix):

There are two cat ears so you have to put that drawing and the associated coordinates on the window twice just as you did with the eyes.

Directrix (directrix):

@dopegyal_ What are the two corrected head coordinates?

Directrix (directrix):

Letters for Ears

Directrix (directrix):

Right Ear -- Need the Lengths M to N (1,10) to (2,10) N to G (2,0) to (2,8) G to O (2,8) to (1,9) O to M (1,9) to (1,10)

Directrix (directrix):

Left Ear -- Need the Lengths K to L (-2,10) to (-1,10) L to P (-1,10) to (-1,9) P to I (-1,9) to (-2,8) I to K (-2,8) to (-2,10)

Directrix (directrix):

I think we did the eyes yesterday and that they were all 1.
