Tangent Perimeter Challenge

CBSE Class 10 · Solve it one decision at a time. A wrong pick earns a nudge, never the answer.

Step 1 of 8

The problem

A circle touches ABAB at P,P, ACAC at Q,Q, and BCBC at R.R. If AP=10 cmAP=10\text{ cm} and BC=8 cm,BC=8\text{ cm}, find the perimeter of △ABC.\triangle ABC.
APQBRCGiven: AP = 10 cmBC = 8 cmTrace the two tangents from A

Step 1 · Your move

Look only at vertex AA. Which two tangent segments start from AA?
