Triangle Theorem These three special properties can be considered the triangle theorem and are unique to these special right triangles The hypotenuse (the triangle's longest side) is always twice the length of the short leg;The 30°–60°–90° triangle is the only right triangle whose angles are in an arithmetic progression The proof of this fact is simple and follows on from the fact that if α, α δ, α 2δ are the angles in the progression then the sum of the angles 3α 3δ =Justification The triangle was originally an equilateral triangle with three 60° angles The equilateral triangle was split down the middle, so α = 30° The other two angles on the side were not changed, so β = 60° Remember that the angles in a triangle must sum up to 180 ° Notice that 30° 60° 90° = 180° 1 cm cm 3 30° 60° 2 cm
