Answer:
A. Intersecting chords
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. !
