Summary of congruent triangles: Literally just a triangle being the same as another triangle

@@irrelevantonyt and what you can do with it like understanding the formula of pythagoras

Its fairly basic if I do say so myself

pretty simple, if something is congruent it means its the same. same triangles and stuff that is explained because of that simple rule

Basic concept, I know if you are willing to learn it, you are smart enough. A triangle being the same as another.

Anything that can help you in math is inherently a good thing, fair play to you!

@@dandanthedandan7558 Same. I was mindblown by that. Its such a random thing, but it makes so much sense. It makes me wonder, how in the hell did those guys discover that way back then? What kind of line of thought leads you to that? Do they just ... Sit down and do random things until they discovered it? It is amazing.

​@@aname6794I suggest watching Veritasium videos if you want a quick lesson on the history of abstract mathematics, shit gets wild lol

Yeah, literally just define concepts and build upon them. First you start with a unit circle with its center on the origin of X and Y axes, insert a radius with a length of one in the center such that it touches the edge. The horizontal distance of the end of radius from the Y axis is the cosine, and the vertical distance the end of the radius is from the X axis is the sine, and with the radius as the hypotenuse you get a right triangle. You can figure out things like the length of chords being directly proportional to the radius and their length is like 2cos(angle)*radius or 2sin(angle)*radius if you draw a line from the center to the chord’s endpoint, depending on which orientation you positioned it (assuming completely vertical or completely horizontal). And the distance the center of the chord is from the edge of the circle is like (1 - sin or cosin (angle)) * radius

Omg Will‼️‼️

@@meltyholic i you like this video check out this ukposts.info/have/v-deo/aXOCmnueboeQ25s.html

Ancient Greeks actually modeled most of their math purely in Geometry as it was seen as the best natural mode of math. They believed most, if not all, math could (or simply should) be solved with a ruler and compass. There are actually some not-frequently-taught techniques that are similar to the ones shown in the triangle vid about drawing shapes using a ruler and compass that in modern times would look off without the foundational mathematical knowledge. In addition: “Squaring” numbers literally meant using squares to calculate the squares of numbers and solving quadratic equations involved completing the square by similar means. Of course using Geometry alone didn’t give them insight into concepts like imaginary/lateral numbers and a lack of coordinate based systems also didn’t leave too much room for discovering negative numbers in their systems. These limitations followed mathematicians into medieval and renaissances Europe until a few key mathematicians tried solving the general equation for a cubic (and quadratic besides). There’s a few UKposts documentaries/essays that go further on these topics and they’re quite interesting with how weird history has treated math as a profession and science.

There's some 200 intuitive ways to show pythagoras theorem, it's been getting remixed for thousands of years now :D

@@alexnoman1498 my worldview getting cracked tf open by this, meanwhile my boring ass maths classes literally just had me memorize Pythagorean and never showed any of these awesome models. Not that I had to see them to know how to use it, but now I totally get how it works and that's satisfying

True, but it’s probably cuz this is teaching things from a foundational and very mathematical point of view, rather than a simplified understanding for high schoolers to pass their tests on.

@@AlexisAlexander646 People tried to understand it from the most fundamental level for thousands of years.

@@fatitankeris6327 Exactly. My point is just that the way mathematicians might explain these concepts in some very detailed form is not exactly the same as a high school teacher teaching teenage students a definition and a few problems on a test just for them to forget one week later. I just find this video to be pretty impressive in showing how these "basic" concepts can actually be very complex in the world of geometry and math.

My brain go "mmmm geometry.. Look good."

Watching "history of the entire world i guess" to study for a world history exam energy

I was just joking earlier that if I were to become a math teacher I would play this video asap while discussing potential career paths lol Imagine though that'd be based

Its pretty distracting tho so maybe a more chill version of this would be better for actually learning

@@A_Yk. also it doesnt really explain anything. Playing this video along with some commentary to explain whats going on would be nice. I don't think anyone just learning a topic would understand Pythagoreans Theory just by seeing the numbers and that triangles make a square. It's not a super difficult subject under normal teaching circumstances but something like this would just make it so much more difficult

It's just like the hypnograms and some mk-ultra shit.

​@@choog2752 It's from a teacher aid video from the 60's and 70's. The actual video makes good use of meshing vector graphics and photos together with a voice over. It's amazing that the best schools can do nowadays is print out the explanation on black and white copy paper when these exist from the 70's.

My favorite is 2:53

Well yeah, of course it's awesome! Defining a circle using triangles, tiling space using triangles, and demonstrating the tesselating pattern of a particular fractal, _all simultaneously!_
