Let’s consider a right-angled triangle. There are \(3\) sides, which are the Hypotenuse, the Opposite side and the Adjacent side. The longest side is known as the Hypotenuse, the side opposite to the angle is the Opposite side and the side where both hypotenuse and opposite side rests is the Adjacent side.
