So we're asked to compare and contrast the two different types of statements that we use in geometry, postulates and theorems.
00:06
A postulate is a statement that is accepted as truth without proof.
00:10
This is something that is easy to understand using simple mathematical reasoning.
00:15
An example would be if we look at a line, if i take a line segment and i call it segment a, c.
00:29
And i have a point somewhere in between a and c called b.
00:35
Then i can imagine that the length of a, b, plus the length of b, c is equal to the length of a, c.
00:44
This is our segment addition postulate.
00:47
So this is pretty easy to understand.
00:48
We don't have to prove that this is true...
