Question

Fig. 3.38
3.
In fig 3.39 chord AB chord CD,
Prove that,
arc AC = arc BD
Let's lear​

Answer 1

Answer:

chord AB ≅ chord CD

∴ m(arc AB) = m(arc CD){Corresponding arcs of congruent chords of a circle (or congruent circles) are congruent}

Subtract m(arc CB) from above,

m(arc AB)– m(arc CB) = m(arc CD) – m(arc CB)

⇒m(arc AC) = m(arc BD)

⇒arc AC ≅ arc BD
