In the figure, two tangents RQ and RP are drawn from an external point R to the circle with centre O. If ∠PRQ = 120°, then prove that OR = PR + RQ.
Question
Solution 1
Sure, here is the step by step solution:
Step 1: In the given figure, join OQ, OP and OR.
Step 2: Since the tangent at a point to a circle is perpendicular to the radius through the point of contact, ∠ORQ = ∠ORP = 90°.
Step 3: Now, in triangle ORQ and ORP, we have ∠ORQ = ∠ORP.
Step 4: Also, ∠OQR Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
