The measure of an angle formed by blank is half the sum of the measures of the intercepted arcs.
a. intersecting chords
b. a chord and a radius
c. interesting radii

A. Intersecting chords

Step-by-step explanation:

A chord is a line drawn from a point inside a circle, and an intercepted arc is the arc whose endpoints are on the angle and which is inside the inscribed angle.

Inscribed angles are formed when two chords intersect each other.

When two chords intersect then inscribed angles are formed.

From theorem of inscribed angle:

"The measure of an inscribed angle= to 1/2  the measure of its intercepted arc"

Hence option A is correct

The measure of an angle formed by intersecting chords is half the sum of the measures of the intercepted arcs.  !

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
