WebRight-Angled Triangle. The triangle of most interest is the right-angled triangle. The right angle is shown by the little box in the corner: Another angle is often labeled θ, and the three sides are then called: Adjacent: adjacent (next to) the angle θ; Opposite: opposite the angle θ; and the longest side is the Hypotenuse Web30-60-90 Right Triangles. Hypotenuse equals twice the smallest leg, while the larger leg is √3 times the smallest. One of the two special right triangles is called a 30-60-90 triangle, after its three angles. 30-60-90 Theorem: If a triangle has angle measures 30 ∘, 60 ∘ and 90 ∘, then the sides are in the ratio x: x√3: 2x.
