Question 1 of 6
Assertion (A): Sides PQ = 6 cm, QR = 4 cm and ∠P = 30° always determine one triangle.
Reason (R): An arc of radius 4 cm centred at Q can meet the 30° ray from P at two points.
Two possible third verticesA fixed ray from the left endpoint and equal-radius segments from the right endpoint locate two possible third vertices.PQRS6 cm4 cm30°
