Detailed Solution

Concept- We'll start by drawing a right-angled triangle and listing its sides. Then we'll apply Pythagoras' theorem to determine what the longest side of a right-angled triangle is called.
First, draw a right-angled triangle here. A right-angled triangle is a triangle in which one of the angles is 90 and the sum of the other two angles is 90.

The perpendicular, base, and hypotenuse are the three sides of a right-angle triangle. Pythagoras theorem also provides a relationship between the base, perpendicular, and hypotenuse of a right-angle triangle. According to Pythagoras' theorem, the square of the hypotenuse equals the sum of the squares of the base and perpendicular sides of a right angle triangle.
As a result, the longest side of a right-angled triangle is referred to as the hypotenuse.
Here, in

is the hypotenuse and it is just opposite to the right angle i.e.

.
Using Pythagoras theorem in

, we get

is known as the hypotenuse and is the right-angled triangle's longest side.
Hence, the correct option is option 1.
