if a triangle is acute, then the triangle is equilateral
A theorem is proven. An example is The "Pythagoras Theorem" that proved that for a right angled triangle a2 + b2 = c2
Pythagoras proved it, but it may well have been discovered and used before his time.
Always true. To see this draw the circle which passes through the three points of the triangle. Reproduce the reflection of the triangle on the hypotenuse (which passes through the centre). Then use the theorem of intersecting chords of a circle to give the result immediately. It's also simply proved by algebra.
Axioms cannot be proved.

There is a legend that whoever flies in the zone of the Bermuda Triangle disappears forever. This has happened to people who flew in this area, but it hasn't been proved if it's just a coincidence.
Pythagoras was an ancient Greek mathematician who proved that the hypotenuse of a right angle triangle when squared is equal to the sum of its squared sides.

One example of a statement in geometry that can be proved is the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This theorem can be proven using geometric methods such as constructing squares on each side of the triangle.
If you mean Pythagoras then he was an ancient Greek mathematician who proved that for any right angle triangle that when its hypotenuse is squared that it is equal to the sum of its two squared sides.
