Can an inscribed angle be an obtuse angle?
Yes, an inscribed angle in a circle can be an obtuse angle. In fact, there are three possible scenarios for inscribed angles in a circle based on their relationship with the intercepted arc:
Acute Inscribed Angle: An inscribed angle whose measure is less than that of the corresponding arc.
Right Inscribed Angle: An inscribed angle whose measure is exactly half that of the corresponding arc, creating a 90-degree angle.
Obtuse Inscribed Angle: An inscribed angle whose measure is greater than that of the corresponding arc.
For an inscribed angle to be obtuse, it must span more than half of the circle's circumference. In other words, the measure of the corresponding arc must be less than 180 degrees, making the inscribed angle larger and obtuse.
So, obtuse inscribed angles are a valid geometric possibility within the context of inscribed angles in circles.
