A self-evident truth is one for which one does not need confirmation by mutual assent, eg. that one is a man or a woman, that one is alive, that one's eyes are a certain hue, that one thinks, breathes, eats and prefers freedom to slavery.
Euclid used self-evident truths in his book, the "Elements", to base his system of geometry, logic and proportion upon, in part. Looking down from an airplane, one can see just how Euclidean our patterns of culture still are in our geometric farms and cityscapes. Look around you at all the squares and rectangles and triangles, cones and so forth -- Euclid's "Elements" is the 2nd highest bestseller of all time, right after The Bible. It was well-known to our country's founding fathers, Lincoln used it to hone his reasoning skills as a lawyer, and one should study it thoroughly if one has not done so already. That and Calculus are the major building blocks of modern culture -- all the rest is disposable decor and the trappings of advertsing.
In mathematics, certain things follow from the laws and rules of algebra, eg.
if I propose that
a+b = a*b = c, then
a+b-b = a*b -b
a = b(a-1)
a/(a-1) = b and b has been isolated and DEFINED in terms of a and 1.
Because both addition and multiplication (the two operators of the hypothesis) are subject to the Law of Commutation, and because I could have subtracted a instead of b first, we now know also that
b/(b-1) = a and a has been isolated and DEFINED in terms of b and 1.
Let b=10. Then
10/(10-1) = 10/9 = a
Does
a + b = a* b = c?
10/9 + 10 = 10/9 * 10 = c?
10/9 +90/9 = 100/9 is TRUE = c√.
And I have just NEUTRALIZED the operators of Addition and Multiplication against one another, logically, and arrived at a new set of numbers in which a and b can equal any related or co-defined numbers but 1 (or zero would result in the denominator, which is undefined).
The TRUTH of my method and CONCLUSION is self-evident to me, and with practice and/or study, may be so to you as well.
Self-evident truths refer to things that need no explanation; they are obvious. An example of one might be that you will be cold if you don't wear your coat when it is snowing.
life, liberty and the pursuit of happiness
From "we hold these truths to be self evident" means these truth require no proof or evidence.
That all men are equal

"We hold these truths to be self-evident..." comes from the US Declaration of Independence.
The correct phrase is "We hold these truths to be self-evident,...." The primary author of the United States Declaration of Independence was Thomas Jefferson.
Things that should be obvious, to a thinking person.
Self-Evident
The concept of self-evident truths comes from the Enlightenment thinkers, primarily John Locke. It is used in the Declaration of Independence as a means of illustrating that the human rights Jefferson was writing about were morally virtuous, unarguably. (Although there is room for debate, in truth, this was the point of using the term self-evident).
"We hold these truths to be self-evident..." comes from the US Declaration of Independence.
The phrase "we hold these truths to be self-evident" means that the truths mentioned, which come after that famous phrase, do not need to be explained, defended, or rationalized. "Self-evident" means that the thing provides its own justification just because it exists.

you [should] assume the following is true
The Declaration of Independence.
Self evident means obviously true in itself, without need for justification. "We hold these truths to be self-evident, that all men are created equal..." The instinct for survival is self-evident, but instincts can be overridden by logic or emotion.
The colonists believed that the truths that were self-evident were: 1)All men are created equal, 2)That they are endowed by their with certain unalienable rights, 3)That among these are Life, Liberty, and the pursuit of Happiness.
