Tangents PA and PB from P are at right angles to each other and PA = 6 cm. Find the length of the chord AB.

Class 10Tangent Lengths and IncirclesGeometry

A6 cm
B $32 c m$
C $62 c m$
D12 cm

Step-by-Step Solution

PA = PB = 6 cm and ∠APB = 90°, so AB is the hypotenuse of right triangle PAB:

36 + 36 = 62

cm.

Answer: C)

62 c m
