Answer: A basic theorem for finding the third length of a right angle triangle is the Pythagoras Theorem.
In a right angle triangle, the slant and usually longest side is called the Hypotenuse while the other two sides are Opposite and Adjacent.
The Pythagoras Theorem States:
[TeX]hypotenuse^{2} = opposite ^{2} + adjacent ^{2}[/TeX]
Step-by-step explanation:
If for example, we are given the other two sides as 3 and 4 respectively,
Using
[TeX]Hyp^2=Opp^2+Adj^2[/TeX]
[TeX]Hyp^2 =3^2+4^2=25[/TeX]
Hypotenuse = [tex]\sqrt{25}[/tex]=5
These set of numbers (3,4,5) in this that satisfies the theorem are called Pythagorean Triples
