After all, a triangle is a rectangle with one side of zero length.

I think you mean a quadrilateral.

That is indeed what I meant, Geoff, which is why I corrected myself while addressing William’s assertion about the triangle in question being isosceles.

After all, a triangle is a rectangle with one side of zero length.

I think you mean a quadrilateral. A rectangle has four 90 degree angles. A quadrilateral could have two 180 degree angles and two zero degree angles. A triangle's angles always add up to 180 degrees, so it can have two right angles separated by a zero length side, and would appear like this: ______________________*

It would be difficult to distinguish it from a triangle with one angle of 180 degrees, and two of zero degrees. However, the former would, of course definitely be an isosceles triangle while the latter may not.

*Actually this is the quadrilateral I've described, but I bet you didn't notice!

An isosceles triangle.

A rectangle with one side of zero length would be a right-angled triangle. I should, of course, have said a quadrilateral with one side of zero length, which could be isosceles.

Please also consider that the sum of the internal angles in a quadrilateral is 360°, but the sum of the internal angles in a triangle is only 180°.

After all, a triangle is a rectangle with one side of zero length.

An isoceles triangle.

Hmm.

I wonder what angles are involved for that.

Please consider too a quadrilateral where the angle between two of the sides is 180 degrees.

I realized, after I had got the result, that I had in error put 'triangle' instead of 'rectangle'.

Do we actually need all those different names for polygonal variants? After all, a triangle is a rectangle with one side of zero length. In a similar vein, a pentagon can be regarded as a decagon half of whose sides are of zero length!

I left it as it had been when the experiment had taken place.

Being in error is not good, but it is important not to falsify what actually happened in the experiment.

Here is what Copilot wrote after producing the picture.

Which triangle are you referring to?

The rectangular one, obviously!

Please paint a landscape picture. Please use the file that I have uploaded as a guide to the layout of the composition. Replace the green rectangle with the hilltop town of San Gimigano in the far distance. Replace the blue triangle with Leonardo da Vinci's flying machine flying in the middle distance. Replace the red rectangle with a lady in the style of Botticelli's Primavera, in the foreground, looking towards the middle distance, viewing the flying machine admiringly.

Which triangle are you referring to?

San Gimigano

I presume you meant to type San Gimignano as in your earlier prompt.

Without the n before the a it would be pronounced

/san dʒimiˈgaːno/

instead of

/san dʒimiɲˈɲaːno/

One gets the whole picture with a white border.

Alternatively, the full field template is good for a square picture if one is willing to lose some of the detail at the edge to being cut off as being in a bleed area.

The computer has been off for a while. Now rebooted.

Try going back to a simpler prompt, as for the beautiful painting from Tuesday 9 January 2024.

https://punster.me/serif/viewtopic.php?pid=3876#p3876

Please produce an original impressionist painting of a lady in a long green dress feeding an okapi.

I got some pictures but they did not have that impressionist look. More like stills from a 1950s colour movie.

After trying various things I got some more pictures and this one is the best in my opinion, but it does not seem to me to have that impressionist look.

Along the way I received some adverts for impressionist style prints.

Also, some links, which I include here.

and

https://punster.me/serif/viewtopic.php?pid=4018#p4018

have some beautiful pictures.

Today, using Bing Chat AI, as before, I tried the prompt

Please produce an impressionist painting in the style of Pierre-Auguste Renoir of a lady facing forward with long hair flowing loosely down both sides of her body in front of her.

But the results were a mixture of like modern photographs and some line drawings.

I tried three times, with a New Topic reset before each attempt.

I then tried using just the surname Renoir, yet similar results.

Please produce an impressionist painting in the style of Renoir of a lady facing forward with long hair flowing loosely down both sides of her body in front of her.

Similar results again.

So I tried with no artist named, as in the first of the two posts referenced earlier in this post.

Please produce an impressionist painting of a lady facing forward with long hair flowing loosely down both sides of her body in front of her.

Still the same.

So I am wondering why such beautiful impressionist style pictures are not being generated.

I used a New Topic reset before each attempt.

I wonder if some change has been made to the system.
