a circle is centered on point B. points A, C and D lie on its circumference. if ABC measures 70 what does ADC measure

The correct answer is 35 degrees
A central angle is twice any inscribed angle subtended by the same angle.
The following four properties and their proofs were introduced: Property 1: The angles at the center and at the circumference of a circle subtended by the same arc. Property 2: Angles at the circumference are subtended by a diameter. Property 3: Angles at the circumference of a circle subtended by the same arc.
Circles have three main parts, which children will learn about: radius, diameter, and circumference. The radius (r) is the distance from the center to the circumference of the circle.
