In Euclidean geometry, a rhombus(◊), plural rhombi or rhombuses, is a simple (non-self-intersecting) quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond, after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (see Polyiamond), and the latter sometimes refers specifically to a rhombus with a 45° angle.
Every rhombus is a parallelogram and a kite. A rhombus with right angles is a square.
The word "rhombus" comes from Greek ῥόμβος(rhombos), meaning something that spins, which derives from the verb ρέμβω (rhembō), meaning "to turn round and round". The word was used both by Euclid and Archimedes, who used the term "solid rhombus" for two right circular cones sharing a common base.
Can you see it in this way
Life is just a long day
In the journey of ourselves
But there's so much we can do
To believe in and make true
And all depends on you
So you, so you keep on dreaming by yourself
Cause:
Where we live, how we die
It's just a thing to see outside
Real truth it's inside
It's what we want to be
So you've got to win, win for yourself
So you've got to win
No one seems to understand
What's the point of our life's plan
The aim we're living for
So they scream into our ears
Stiring up our biggest fears
In this life we're gonna face
But you, but you keep on dreaming by yourself
Cause:
Where we live, how we die
It's just a thing to see outside
Real truth it's inside
It's what we want to be
So you've got to win, win for yourself
So you've got to win
So I leave you with my own advice
Ain't no one better than you to know what is right
In your feelings there is your plan
And in your life you're the real boss, man
Keep on searching in yourself
Ain't no answer in someone else
So you've got to win, win for yourself
So you've got to win
