<h2>Problem statement</h2>
|
||||
|
||||
<p>
|
||||
The diagram above shows an equilateral triangle inscribed in a rectangle
|
||||
in such a way that the two have a vertex in common. This subdivides the
|
||||
rectangle into four disjoint triangles.
|
||||
The original equilateral triangle is shown in white
|
||||
in the diagram; the other three are shown in color.
|
||||
|
||||
<p>
|
||||
<b>Proposition</b>
|
||||
<em>
|
||||
The area of the blue triangle equals the sum
|
||||
of the areas of the two pink triangles.
|
||||
</em>
|
||||
|
||||
<p>
|
||||
The trigonometric proof is quite straightforward. I don't
|
||||
know of a classical proof <i>a la</i> <span class="name">Euclid</span>.
|
||||
(Well, actually I haven't tried much.)
|
||||
If you can think of a neat non-trigonometric proof, let me know. I will
|
||||
put it here with due credit.
