Question

In a right angled $△$ABC, right angled at B, which of the following is true?

• A. AB² = AC² + BC²
• B. AC² = AB² + BC²
• C. BC² = AB² + AC²
• D. None of these

Answer 1

The correct option is B

AC² = AB² + BC²

In a right angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.

So, In the right angled $△ABC,$ right angled at $B,AC$ is the hypotenuse and $AB$ and $BC$ are the other two sides.

Hence, ${AC}^2={AB}^2+{BC}^2$
