What are the different types of inscribed angles

The video tutorial discusses inscribed angles, starting with a review of central angles. It explains that a central angle has its vertex at the center of a circle and its measure equals the arc it subtends. The tutorial then introduces inscribed angles, which have their vertex on the circle. The measure of an inscribed angle is half the measure of the arc it subtends. The video covers three cases of inscribed angles and provides examples to illustrate the concept.

What is the measure of a central angle in relation to the arc it subtends?

• Equal to the arc measure

• Unrelated to the arc measure

• Half the arc measure

• Twice the arc measure

Where is the vertex of an inscribed angle located?

• On the circle

• Outside the circle

• Anywhere inside the circle

• At the center of the circle

How does the measure of an inscribed angle compare to the arc it subtends?

• It is half the arc measure

• It is equal to the arc measure

• It is twice the arc measure

• It is unrelated to the arc measure

If an arc measures 100 degrees, what is the measure of the inscribed angle subtending it?

• 100 degrees

• 200 degrees

• 25 degrees

• 50 degrees

What is the arc measure if the inscribed angle is 13 degrees?

• 39 degrees

• 13 degrees

• 26 degrees

• 6.5 degrees
