Question

In a Right Angled Triangle,

Altitude $=12$ cm and Base $=5$ cm. Find the Hypotenuse.

• A. 120
• B. $12$ cm
• C. $13$ cm
• D. $14$ cm

Answer 1

The correct option is C

$13$ cm

In a Right Angled Triangle,

${\text{Hypotenuse}}^2={\text{Altitude}}^2+{\text{Base}}^2$ [Pythagoras Theorem]

$\Rightarrow {\text{Hypotenuse}}^2={12}^2+5^2$

$\Rightarrow {\text{Hypotenuse}}^2=144+25=169$

$\Rightarrow \text{Hypotenuse}=13$ cm
