Let there be a rectangle ABCD
On each side of the rectangle, ANY point is taken. (The point must lie on the side. You can’t produce a side backwards, and then take a point on it.)
Let the points be P, Q, R, S on the sides AB, BC, CD, DA respectively.

Now prove:
2(AC)<=PQ+QR+RS+ST
[Hint : for a triangle ABC, AC
When you’ve solved this one, try proving it without using the theorem given in the hint.

On the religion and spirituality section many defenders of evolutionary theory say that humans evolved from an "apelike creature".

Given that we are, in fact, apes, and our closest relatives are also apes, isn't it reasonable to assume that the common ancestors of all ape species would also have been in the hominoidae superfamily?

Why are so many so keen to call our ancestors "ape like creatures" rather than just calling an ape an ape?

Or do humans belong to some other family of primates I've never heard of?
