Download Solution PDFചിത്രത്തിൽ,
PW = PZ (∵ ഒരു ബാഹ്യ ബിന്ദുവിൽനിന്ന് ഒരു വൃത്തത്തിലേക്ക് വരച്ച സ്പർശരേഖകൾ ഒരേ നീളമുള്ളതാണ്)
PW = PZ = x സെമി എന്ന് കരുതുക
സമാനമായി,
⇒ QW = QX
⇒ RX = RY
⇒ SY = SZ
∵ PW = x ,
⇒ QW = PQ – PW = (2 – x) സെമി
ഇപ്പോൾ , QW = QX = (2 – x) സെമി
∵ QX = (2 – x) സെമി,
⇒ RX = QR – QX = 3 – (2 – x) = (1 + x) സെമി
ഇപ്പോൾ , RX = RY = (1 + x) സെമി
∵ RY = (1 + x) സെമി,
⇒ SY = RS – RY = 4 – (1 + x) = (3 – x) സെമി
ഇപ്പോൾ , SY = SZ = (3 – x) PS = PZ + SZ = x + (3 – x) = 3 സെമി
