In a right-angled triangle, which side is always directly opposite the right angle?

1. The three sides of a right-angled triangle are named relative to the angle you are working with. 2. The hypotenuse is always opposite the right angle and is always the longest side. 3. It keeps that position whichever of the other two angles you choose to look at. 4. The opposite and adjacent sides do swap places when you switch angle. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 5: Trigonometry_
