Assertions

h² = p·q

Evidence

Condition - theorem of Pythagoras:

The height divides the triangle into two right angled triangles: ahp and bqh. So, the following is obtained according to the theorem of Pythagoras:

h² + p² = a²

h² + q² = b²

 

Hypotenuse squared, is the same as both hypotenuse sections added to the second power:

c² = (p+q)²

c² = p² + 2pq + q²
