Perimeter of Triangle PQR = 16 cm , A circle touches the side qr of triangle pqr at a and sides pq and pr on producing s and t respectively is ps = 8cm
Step-by-step explanation:
PS = PT ( Equal Tangent)
PS = 8 cm
=> PT = 8 cm
PS + PT = 8 + 8
=> PQ + QS + PR + RT = 16 cm
QS = QA & RT = RA ( equal Tangents)
=> PQ + QA + PR + RA = 16 cm
=> PQ + QA + RA + PR = 16 cm
QA + RA = QR
=> PQ + QR + PR = 16cm
=> perimeter of Triangle = 16 cm
