Question

In figure,chord BC produced to point P and PA is a tangent to the circle at A. prove that PB×PC = PA² (correct answer marked as brainliest)

Answer 1

Answer:

ExplaPA =PB using theorem

so PB =4 cm

now angle PAB = 180-135 using linear pair of angles

so angle pab is 45

now pa = pb so LA = LB

using angle sum property angle p = 90

now use Pythagoras theorem
