What is the relationship for two inscribed angles with the same endpoints

The video tutorial covers the concept of inscribed angles in geometry. It begins by defining inscribed angles and explaining their properties, such as having endpoints on a circle. The tutorial then discusses how the measure of an inscribed angle is half the arc it subtends. It further explains that inscribed angles with the same arc are equal. The video concludes with a summary of these key points.
