WebWe get two triangles: Δ ABD and Δ BCD. The measure of internal ∠ ABC is just the sum of the measures of ∠1 and ∠2. The measure of ∠ ADC is the sum of measures of ∠3 and ∠4. Meanwhile, ∠ BAD and ∠ BCD are shared between triangles and the quadrilateral. When we add the angles of both triangles together, 180° + 180° = 360°. Web11 jan. 2024 · It has 12 interior angles Sometime during the mid 1600s, a mathematician felt the need for a descriptive word for a 12-sided polygon. The word dodecagon comes from the Greek, dōdeka-, which means 12, and + -gōnon, which means angled. Dodecagons can be regular, meaning all interior angles and sides are equal in measure.
WebA skew decagon is a skew polygon with 10 vertices and edges but not existing on the same plane. The interior of such an decagon is not generally defined. A skew zig-zag decagon has vertices alternating between two parallel planes. A regular skew decagon is vertex-transitive with equal edge lengths.
