Yes and the angles around the point of intersection add up to 360 degrees.
primary chords are chords witch are i dont have a clue

apex= True
Not true. If the associated central angles are equal, the two chords would be equal.
Not unless the chords are both diameters.
Sometimes
true
It is the measure of half the intercepted arc.
If two chords intersect within a circle, the product of the two segments of one chord equals the product of the two segments of the other chord. In short, if two chords intersect in a circle, their length is equal.
yes
yes
There are many angles inside a circle. You have inscribed angles, right angles, and central angles. These angles are formed from using chords, secants, and tangents.
15pi. after you add.
