Triangle in a triangle (Posted on 2017-08-28) Difficulty: 1 of 5
If you have a triangle with sides A<B<C
and a smaller triangle with sides a<b<c,
where a<A, b<B, and c<C,
will the smaller triangle always fit entirely within the larger one?

You don't even need a triangle that extreme.  A triangle with sides 3,3,5 has its shortest altitude of sqrt(11)/2 = 1.658.

The equilateral triangle 2,2,2 has all its sides smaller and has altitudes of sqrt(3) = 1.732, which won't fit in the 3,3,5 triangle.
