Thank you for the video, once again
From 6:00, when you have demonstrated EA=EC=ED, then just consider the circle centred in E and passing thru A, C and D. Angles ACD and AED intercept the same arc AD. And so angle X = 60/2.

Very nicely done indeed! 👍👍
But at 2:25, I think it would be wise to avoid using ABC when talking about any triangle in general. It caused me a little confusion at first because I thought you're referring to the triangle ABC in the problem.

Let's assume that a, b, c are the three distinct side length of a triangle so that the area of the triangle is 1 unit². Prove that b >_ 2.( a>_ b>_c)

Bro this problem can also be done easily by using sine rule and some manipualitions 😊😊

I do not understand. Are the areas of the triangles ADC and DBC the same? The area of ADC = 1/2*AD*CD*sin(45) = 1/2* DB*CD*sin(135)? Therefore AC = BC?

AED triangle seems not really equilateral 😮😅

I think there is a more simple way to solve
