Question

Why do you need absolute values when you write expressions for the lengths

of the legs, but not when you write the relationship in terms of the
Pythagorean Theorem?
please answer quickkk

Answer 1

Magnitude or distance is never negative

Explanation:

You need absolute values when you write expressions for the lengths

of the legs because lengths or distance cannot be negative

But when you write relationship in terms of the Pythagoras Theorem you need to maintain the plus or minus values.

This is because the values do not represent distance or magnitude.

They may represent position relative to a reference point.
