... Lines also have special relationships. Intersecting lines that form right angles are called perpendicular lines. Lines that are in the same plane, but do not cross, are called parallel lines. If two parallel lines are cut by a third line, or a transversal, all of the acute angles are congruent and a ...

... ∠OCA = θ, ∠OBA = φ. So AB subtends ∠ACB = θ + φ at the circumference. In ∆AOC, ∠AOC = π − 2θ (angle sum is π), and similarly ∠BOC = π − 2φ. The three angles are O sum to 2π; the two just mentioned sum to 2π − 2θ − 2φ. So ∠AOC = 2(θ + φ) = 2.∠ACB. // Note that if the chord goes through the centre, th ...
