The video tutorial explains inscribed angles in a circle, focusing on angles H and K with endpoints on arc PQ. It demonstrates that inscribed angles with the same endpoints are congruent, meaning they have equal measures. The tutorial emphasizes that the location of the inscribed angle on the circle does not affect its measure, as long as it shares the same endpoints on the arc. This concept is reinforced through examples and explanations, highlighting the geometric properties of inscribed angles.

How does the position of an inscribed angle affect its measure?
