| Since points A, B, C D lie on a circle, the angle DAB – inscribed, rests on the arc BD.
AD – continuation of the side of the angle ОАВ, means <DAB = 36 °
BOD corner – central, rests on the BD arc.
The degree measure of the central angle is twice the degree measure of the inscribed angle,
resting on the same arc.
Means: <BOD = 2 * <DAB = 2 * 36 ° = 72 °.
