Puzzle Area of a Triangle in a Square

[@sbjani2006]

Wonderful. I like your solution as an ORIGAMI fan .

Thank you! Paper folding has a lot of math. You might like the clip on this channel about perfect Pentagon by paper folding.

@@UjjwalRane Yes. I have done that fold from another KZbin video . Thanks .

[@HedroomMax]

It only works if the corresponding internal angle of the triangle is 45 degrees.

[@nikitasingh8303]

How to calculate sir ?

[@Ranoake]

I don't understand why folding is an analytical solution, it could just be a coincidence?

[@UjjwalRane]

We need not actually fold the paper by plotting the figure and cutting it. It can simply be imagined. The key is: we have an angle 45° which is HALF the right angle. THAT suggests it is a fold to create a complete overlap. The animation is to make the visualization convenient for the reader.

Hi can you explain how to calculate,and if it gives us 80 degrees and 40 degrees what can we do if you explain that Will be good

[@UjjwalRane]

80° in place of 70° angle is not going to make any difference, but if the angel of 45° is disturbed, the paper folding will not give coinciding vertices D' and B'

[@aksikhoyske131]

Why we should do, if angel will be 40° or another number?

[@UjjwalRane]

In all cases the second approach will always work. But we should always keep an eye for special values that lead to some interesting, fun paths to the solution!

@@UjjwalRane hi can you explain someone has given me question like that but degrees are 80 and 40 how to find in this situation

[@JAVA508]

Hey does the angle answer is 67° 😅 pls tell ❤

[@UjjwalRane]

No. It works out ti be 65°
