The video tutorial covers inscribed angles in geometry, explaining their properties, such as having a vertex on the circle and sides that are chords. It discusses how the measure of an inscribed angle is half the intercepted arc and introduces concepts like right angles formed by inscribed angles intercepting a diameter. The tutorial includes examples and problem-solving exercises to reinforce these concepts. Additionally, it covers inscribed quadrilaterals, highlighting that opposite angles are supplementary.

What is the measure of an inscribed angle directly related to?

• Twice the measure of its intercepted arc

• Half the measure of its intercepted arc

• The radius of the circle

• The diameter of the circle
