Higher maths tangent to circle
WebSet OC and OB as x, they are equal because all radii are congruent. OC is perpendicular to AC (line tangent to a circle is perpendicular to the radius drawn to the point of tangency), making OAC a right triangle. OA is the hypotenuse, OC and AC are the legs. So you … WebIn this video I will teach you how to prove that a line is a tangent to a circle using the quadratic formula discriminant. In doing so I will guide you through a step by step method …
