Question

in the figure shows that AB, AC and PQ are tangents to a circle with centre O. prove that the perimeter of triangle apq = 2ab​

Answer 1

Answer:

Tangents drawn from the same external point are equal in length.

So, AB=AC=5cm and similarly

PQ=PB+QC

⇒AP+PQ+AQ=(AP+PB)+(AQ+QC)=AB+AC=10cm

So the perimeter of triangle APQ is 10cm

So option A is the right answer.
