WebFeb 9, 2024 · Alternative (J. Pahikkala): Since 72∘ 72 ∘ and 60∘ 60 ∘ can be constructed, 12∘ =72∘−60∘ 12 ∘ = 72 ∘ - 60 ∘ can be also constructed. Bisecting 12∘ 12 ∘ gives 6∘ 6 ∘ and bisecting again shows that 3∘ 3 ∘ can be constructed. Theorem 2. We can construct any angle measuring an integer multiple of 3∘ 3 ∘.
