Hope it helps you mate

Thank you

Answer 2

Answer:

Step-by-step explanation:

a) OD is Radius of the circle. [ Radius is the distance between center of circle and any point on the circumference of circle.]

b) AB is Diameter of the circle. [ The line segment joining any two points on the circle and passing through the center is diameter]

c) PQ is Chord of the circle. [ The line segment joining any two points on the circle is called chord. Diameter is the longest chord]

d) ∠ DOB or√DOA is the central angle. [ An angle whose vertex is at center of the circle]

e) Minor arc: arc AXD, arc BD, arc AP, arc PQ, arc BD, arc PB  [A part of circle between two points is called an arc; smaller one is called minor and larger one is called major]

f) Major arc: arc PAB, arc PDQ, arc ADQ

Semicircular arc : arc ADB, arc APQB

m(arc DB) = ∠DOB   [Angle subtended by arc at the center]

m(arc DAB) = 360° -m∠DOB
