Steps for Finding the Tangent of a Circle Step 1: Determine which length is missing in the figure. Step 2: Solve the equation or use the Pythagorean Theorem to find the missing length. Equations and Definitions for Finding the Tangent of a Circle Tangent Line: a straight line that touche...
Let the equation of the tangent line be y= -x +b. Substituting this into the equation of the circle: 2x^2- 2bx+b^2-4=0 . Since the line is tangent to the circle, we have △=(-2b)^2-4*2(b^2-4)=0 Solving for b: b =±2 2. So the equation of the tangent line is ...
