Answer: Statement 1 and Statement 2 are theorems because they can be proved.
Explanation:
A postulate is a statement that is supposed to be true without any proof.
For example Postulate 1:- A line contains at least two points.
A theorem is a true statement which can be prove by using postulates and previous theorems as reason.
Here statement 1 " If two lines intersect, then they intersect at exactly one point."is the theorem for intersecting lines and statement 2 "In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the length of the legs" is the famous Pythagoras theorem.
