Hello Arthur,
Actually the demonstration is completely flawed and lacks credibility.
First of all, want to acknowledge this insistence the true and correct Pi=3.1446 completely ignores and disregards Billy's and the Plejaren's Contact Reports information the true and correct Pi remains unknown. Please address the elephant in the room; why bother attempting to prove Pi=3.1446 when both Billy and the Plejaren have clearly stated this isn't possible?
I've only quoted information directly from the Contact Reports while those who continue to push Pi=3.1446 have absolutely NO Contact Report credible references. All the supposed proof Pi=3.1446 is extracted from elsewhere, and completely ignores the obvious information about Pi shared by Billy and the Plejaren namely that true value of Pi remains unknown. How can anyone who accepts the authenticity of Billy's information, ignore the Contact Report references about Pi? Unbelievable!
Further conventional mathematics proves Pi=3.1446 is physically impossible, and every mathematician, scientist and engineer in the entire world has known for the last 2000 years Pi=3.1446 is nonsense, yet against all odds, you and a token few march on like lemmings over a cliff attempting to prove the impossible Pi=3.1446 but - so be it.
Debunking this faked proof Pi=3.1446 example, requires the two triangles are similar. Rather than offer a compelling detailed algebraic analysis showing how the two triangles are similar, we learn that a piece of software says the two triangles are similar therefore it should be assumed factually correct! Seriously - this is not actually proof in-of-itself.
The request asking for help to prove the two triangles are similar algebraically is priceless because it proves an inability to actually find a valid proof the two triangles are similar (as suspected), therefore if it cannot be credibly demonstrated using algebraic equations, the two triangles are similar, the entire proof Pi=3.1446 falls apart and lacks credibility as is eventually discovered in each-and-every failed proof Pi=3.1446.
Did it not occur the primarily reason there is no algebraic proof the two triangles are similar is because they are actually NOT similar! Maybe that's why no algebraic proof exists demonstrating the two triangles are similar. You think! Had the triangles actually been similar a mathematical algebraic proof would be child's-play to derive. The fact is the two triangles are dissimilar because they have different internal angles as previously stated.
None-the-less offer the challenge to prove two triangles are similar, however the results should be presented as a logic sequence of algebraic equations, and the analysis shared here so it may be legitimized as valid and factually correct. Do the math yourself!
And so the Pi=3.1446 nonsense shall likely continue with more pretty picture proofs or claimed software results none of which is ever backed by actual logical algebraic equations and legitimate analysis to substantiate the results not withstanding the Contact Reports confirm quite clearly, the true and correct Pi remains unknown, which the Know-It-All's completely ignore.
