Tangent TP perpendicular to radius PC

Title .... Tangent TP perpendicular to radius PC

Q1. Tangent TP perpendicular to radius PC

Theory
  • Tangent TP perpendicular to radius PC
Theory
  • If other tangent TQ is drawn, then TP = TQ
  • Proof
    • PC = QC
    • Angle TPC = angle TQC = 90
    • TC is common side of triangle TPC and TQC
    • Hence triangle TPC and TQC are congruent
    • Hence TP = TQ
