The video tutorial covers inscribed angles, central angles, and their relationships with arcs in a circle. It explains that central angles have vertices at the circle's center and are congruent to their intercepted arcs. Inscribed angles have vertices on the circle and measure half of their intercepted arcs. The tutorial also discusses congruent inscribed angles intercepting the same arc and properties of inscribed quadrilaterals, where opposite angles are supplementary.
