Questions & Step-by-Step Solutions

If a tangent from point P touches a circle at point T, and the radius OT is 5 cm, what is the length of PT if PT is perpendicular to OT?
  • Tangent and Radius Relationship – In a circle, a tangent at any point is perpendicular to the radius drawn to the point of tangency.
  • Properties of Right Triangles – Understanding the properties of right triangles can help in solving problems involving perpendicular lines.
