WebAug 22, 2024 · The perpendicular transversal theorem states that if there are two parallel lines in the same plane and there's a line perpendicular to one of them, then it's also perpendicular to the other one. WebFeb 27, 2024 · Now, we determine the equation of a tangent line to a circle: Step 1: Firstly find the equation of the circle and write it in the form, ( x − a) 2 + ( y − b) 2 = r 2. Step 2: From the above equation, find the coordinates of the centre of the circle (a,b) Step 3: Find the slope of the radius –. m O P = y 2 – y 1 x 2 – x 1.
