Question

If in $\Delta$ABC, $\angle$ A = 90${}^o$ then the hypotenuse is

• A. AB
• B. BC
• C. CA
• D. none of these

Answer 1

The correct option is B BC

In $△ABC$,

$\angle A={90}^o$ [ Given ]

Hypotenuse is the longest side of a right-angled triangle and opposite side of the right angle.

$\Rightarrow$ Here, $A$ is right angle and its opposite side is $BC$.

$\therefore$ $BC$ is a hypotenuse of $△ABC.$
