- Angle in a semi circle is a right angle.
Find the value of ∠PQR in the given figure.
In ΔPQR, ∠PQR + ∠QRP + ∠RPQ = 180°
⇒∠PQR + 90° + 32° = 180°
⇒∠PQR = 180° − 90° − 32° = 58°
- The angle subtended by an arc at the centre of the circle is double the angle subtended by the arc at the remaining part of …
