Why can’t we take the square root of a negative number? provide example.

Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0.

because its irrational if you have a negative sqaure root you would have to turn it positive by turning it to a fraction or if it's already in a fraction the you have to switch the side it's on and you could change the negative if it's a whole number that you should make it a fraction by putting a 1 under it

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
