WebA regular hexagon contains six congruent sides and six congruent angles. Let’s use what we know to determine other properties. A number of diagonals is: d = n ( n – 3) 2 = 6 ( 6 – 3) 2 = 9. The sum of the measures of all interior angles is: ( n – 2) ⋅ 180 ∘ = 4 ⋅ 180 ∘ = 720 ∘. The measure of each interior angle: WebSep 7, 2016 · Diagonals of a Regular Hexagon A hexagon is any six-sided polygon, and the sum of its angles is 720°, as we saw above. In a regular hexagon, each angle = 720°/6 = 120° How many diagonals does a hexagon have? Starting from one vertex, two other vertices are adjacent, so 3 vertices are non-adjacent, making possible three diagonals from one vertex.
