Answer 1

Answer:

NOTE:-I will use D in place of B.

Angle subtended by a chord at the centre is double that of the angle subtended by chord on circumference.

Since diameter subtend 180° at centre therefore it subtend 90° at the circumference.

We can say that ∠ACD=90°

Since it given that AC=DC so the base angles are equal.

⇒∠CAD=∠CDA

In triangle ACD-

∠CAD+∠CDA+∠ACD=180°

Let ∠CAD=∠CDA=∅

therefore 2∅=90°

From this, we can conclude that-

∠CDA=∠CAD=45°
