Answer:
|a|² = |b|² + |c|²
Step-by-step explanation:
the pythagoras theorem states that in a right angled triangle, the square of the sum of the hypotheneus side is equal to the sum of squares of the opposite side and adjacent side.
That is,
| HYPOTHENEUS|² = |OPPOSTITE|² + | ADJACENT|²
inorder to use the pythagorean theorem to evaluate this
|a|² = |b|² + |c|²
