If two chords intersect inside a circle, the angles formed are called inscribed angle

NO. They are called Interior Angles.

Step-by-step explanation:

The inscribed angles are those which has its vertex over the circumference. The two chords determine to vertically opposite angles which has the same measure, but its common vertex is in the interior of the circumference. A special case occurs when the vertex is over the center of the circumference, this is called a central angle. There is a third possibility, that is when the vertex is out of the circumference. This angles are called exterior angles. This are the positions of angles relative to a circumference.

yes yes yes yes yes yes yes yes yes

it would rotate about 180 degrees.
