प्रश्न
In the figure, two chords AB and CD of the same circle are parallel to each other. P is the centre of the circle. show that ∠CPA = ∠DPB.
उत्तर
CD || AB (Given)
⇒ CP = OP (Radius)
⇒ AP = PB (Radius)
⇒ ∴ ∠PCD = ∠PAB
⇒ PDC = ∠PBA
Hence, = ∠DPB

Given: ∠PQR and ∠PSR are inscribed in the same arc
Arc PXR is intercepted by the angles.
To prove: ∠PQR ≅ ∠PSR
Proof :
m∠PQR = `1/2` m(arc PXR) .......(i) `square`
m∠`square` = `1/2` m(arc PXR) ......(ii) `square`
∴ m∠`square` = m∠PSR .......[From (i) and (ii)]
∴ ∠PQR ≅ ∠PSR ........(Angles equal in measure are congruent)
