A triangle has three angles and three sides and it is possible for all three angles to be different from each other.
Each angle is defined by two of the sides - which form the rays meeting at the angle's vertex. The third side is the "opposite" side.
The above statement can be proven (eg by the sine rule) for any triangle.
The longest side of a triangle is always opposite to its largest angle.

False because the longest side of a right angle triangle is its hypotenuse which is opposite to its largest angle of 90 degrees.
The hypotenuse is defined as BEING the longest side of a triangle. In a right angle triangle, it is always opposite to the 90˚ angle, because the 90˚ angle is the largest angle of the triangle.
