MCQ
In right-angled $\triangle\text{DEF}$ if $\angle\text{E} = 90^\circ$ then:
  • A
    $DE$ is the longest side.
  • B
    $DF$ is the shortest side.
  • C
    $EF$ is the longest side.
  • $DF$ is the longest side.

Answer

Correct option: D.
$DF$ is the longest side.
In a triangle, only one right angle is possible, hence it is the greatest angle and the side opposite to it is the longest side. Here, the side opposite to $\angle\text{E}$ is $DF$, hence, it is the longest side.
