WebThis formula tells us the shortest distance between a point (π₯β, π¦β) and a line ππ₯ + ππ¦ + π = 0. Since the radius is perpendicular to the tangent, the shortest distance between the center and the tangent will be the radius of the circle. π₯ = 5 This can be rewritten as: π₯ - 5 = 0 Fitting this into the form: ππ₯ + ππ¦ + π = 0 We see that: π = 1 π = 0 WebDec 1, 2024 Β· Tangent drawn from a point P, touches the circle at Q. PQ = 24 cm and OQ = 10 cm Concept used: 1. If a tangent is drawn on a circle from an external point, then at the point of tangency, it is perpendicular to the radius. 2. In a right-angled triangle, Hypotenuse 2 = Base 2 + Height 2 Calculation: According to the concept, β OQP = 90Β°
