The formula for the 2nd and the 3rd case is written as $$\frac{a^2+s^2-as(\sin\theta + \cos\theta)}{2 \sin\theta \cos\theta}$$ which is... -
bob012345 replied to the thread High School Area of Overlapping Squares.Interesting observation! It appears so if both values are within the range of the functions. Looking at ##(a,s)## being (4,5) vs... -

The answers for the first case and the 4th case are symmetric for exchange of s and a. May we expect the same for the 2nd and the 3rd... -
bob012345 replied to the thread High School Area of Overlapping Squares.I worked out the overlap of the two squares as a function of angle. Given ##a## is the half edge length of the original square and... -
bob012345 replied to the thread High School Area of Overlapping Squares.Agreed. Now the larger square is the 1m square. The overlap depends on the relative orientation until ##s## shrinks to... -

$$s=\sqrt{2}/2$$is the minimum value satisfying it though not larger any more. And also $$s=\frac{1}{2\sqrt{2}} $$is the maximum. -
bob012345 replied to the thread High School Area of Overlapping Squares.The next level is if we let the length ##s## of the larger square vary, what range of values of ##s## will your statement not be true? -

It seems not necessary. For any angle configuration we get the same result. -

A figure sure helps. -

Sometimes it's simpler to use degrees rather than radians for the measurement of angles. -
bob012345 replied to the thread High School More similar triangle problems.Well that explains my little mystery from post #18. Here is the curve for the total area of the triangle for c=d normalized to the... -

Regarding post #21, the formula given for area minimizing ##\theta## simplifies to ##\tan\theta=c/d##. The minimum area just becomes... -

All right. Based on post #19, there are the next steps. $$...
