That's an interesting statement. For a lot of teachers, it's a decision based on the level of the class. For a motivated and interested class, teaching the the meaning and reasoning is easy, enjoyable and greatly beneficial. But for a class that just doesn't care (lower ability students) or won't do anything with maths beyond the exam, the priority is to get them through the exam with the highest mark possible. Those students will just need practice and may not care about the reasoning. Plus, we are only seeing a snippet of Eddie Woo's teaching. Maybe he doesn't teach the meanings with every class either. (I'm not wanting to criticise - he's a very engaging and enthusiastic teacher, with very clear explanations! But what you see on KZitem will only be a snapshot of his teaching.)

I'm surprised that he went into such a complex proof, although maybe the math was too advanced for his students. Using his diagram, the total area is (a+b)^2 expanded to a^2 +2ab+b^2.. Adding up the areas of the triangles' area =2ab. Equating the areas yields a*2+2ab+b^2=2ab+c^2. Subtract 2ab from both sides yields a^2+b^2=c^2.

Being a flat earther is more of a thinking process, rather than the belief the earth is flat. Its about not trusting everything you are told at face value but rather using your own logic and perception to discover the world and reality around you and to question the authority that is indoctrinating your psyche. This is a tool that is increasingly being overlooked in traditional western society and hence the need for balance by reinstituting a more critical thinking process. But of course some take it to the extreme and actually think the earth is flat because they themselves can't prove its round

If you take the longitude (the ones that run north and south), there technical definition is that they are parallel at set degree away from the prime meridian at the equator. They are only parallel at the equator do to how they work. They technically not parallel lines (technically sphericalg geometry state no parallel lines exist, but I dont understand spherical geometry enough to understand why. Perhaps they just mean of the lines is as big as the biggest possible straight line). Projected geometry is a lot more complicated, and state that parallel lines intersect, sort of. Basically projected geometry take the fact that the further away something is the smaller and closer to other objects it appears to you. If given infinite eyesight with an infinite flat plane, at some point two infinity long paralle line, no matter how far away from one another, would intersect at a point if you looking at the plane from slightly above it (so your height). This point, the horizon, is called line at infinity and is treated as real as all other points on the plane. All parallel lines meet somewhere on this line, with all non parallel line meeting somewhere on the plane itself. Note that any moving changes the line position (height, rotation, walking, and so on), and extending past this line technically enters spherical geometry (this has been a quick and probably oversimplified version of this problem and projected geometry).

I really liked the amount of engagement this teacher fostered within me in just 10mins. I am an average student. The only reason I was topper during primary school was that none of the math was ever hard. But in middle school the real math hit me. On top of that, the pandemic restricted in-person classes for almost 2 years. Which means my entire 7th and 8th grade went to waste. Our 8th-grade finals were conducted in school and I did not do well in subjects like math, chemistry and computer, my weaker subjects. Except for those, my grades have been more or so alright. Based on the book I got from my seniors we have Pythagoras theorem from 9th grade onwards. I wanted to cultivate an interest in Math. Therefore I am glad I found this teacher. In my school teachers only did the exercises and never told us how it was formed in the first place. If we were unable to understand or do some sums we were expected to go to extra tuition and take help from the teachers. The tuitions were never any better than the schools. The same students would reach home after 6 hours of schooling and then go through 5-6 hours of tuition. No real engagement or interest. As someone with a lot of visual ability, excelling in arts and creativity, I came to know how visually studying benefited me. As I am starting high school I hope to reach greater heights and be more than an average student.

I loved this visual explanation. I love how he broke down each step. He clearly has energy, involves the class, and loves explaining. One thing I wish he explained: how do we know for certain that the c,c,c,c shape in the middle is definitely a square? Is it because we know that if all sides are the same it's automatically a square?
@MafiaCow01

If you're asking the question for yourself, then: We know that all three inner angles of any triangle add up to 180° and that a right angle is 90°. So taking the right angle away from the total, the other two angles add to 90°. We know that a straight line is 180°, so in those corners of the inner square where the two triangles touch, 180° of the straight line minus the two angles (that add to 90°) equals 90°, which is the same for each corner because they're the same triangles we started with. Combine that with knowing the sides are all C, and that defines a square.

You actually don't need the second square configuration. Having established the side length of the square as a+b, there are, in fact, 2 ways to write the area. First is traditional area of a square [(a+b)^2]. Second is adding the area of the shapes that made it [4x triangle (ab/2) + square C (c^2)]. We can equate these areas to give the following: (a+b)^2=4(ab/2)+c^2 Expanding: a^2+2ab+b^2=2ab+c^2 Subtract 2ab from both sides: a^2+b^2=c^2 QED

You could also give an area argument (without having to apply transformations), noting that the total area of the larger square is (a+b)^2 and that the area of just the green portion is 2ab. From here, we know the area of the inner square is a^2 + b^2, so the length of each side of the inner square is sqrt(a^2 + b^2). The Pythagorean theorem follows since each side of the inner square is the hypotenuse of each triangle.

But before rearranging it, couldn't you do (a+b)^2 for the entire area of the square, which is a^2+b^2+2ab, which then has to equal the 4 triangles *AND* c^2? So to figure out the 4 triangle areas, its 4ab/2 = 2ab. So, a^2+b^2+2ab = 4ab/2+c^2 which 4ab/2 is 2ab so a^2+b^2+2ab = 2ab+c^2. Subtracting 2ab from both sides gives you a^2+b^2 = c^2.

of course you could. There are various ways to prove the theorem. But the point is. In order to do that, you need to have learned already how to calculate ( a + b ) ^ 2. I know, this is not hard. But yet. You need to know how to do it, which might not be the case for this kids. His goal was to present an entirely graphical prove. All that is needed is to know how to actually calculate the area of a rectangle given its (simple - that is 1 "letter") side length and by paying attention. Nothing more is needed. The rest is just recognizing that the 4 green rectangles in the first "big square" and in the second figure are the same (just rearranged) and thus can be removed from either figure, leaving you in the first case with the blue suare (representing c^2) and leaving you in the second case with 2 smaller squares representing a^2 and b^2.

Usually when lines rotate they form surfaces. So rotation and translation. Rotation is multiple and translation is add or subtract. So surfaces equals other because of equal rotational symmetry. So integration is some form of rotational symmetry. Essentially when you do integration you are finding the rotational symmetry of numbers. Prime act as vortex.
