Remember, to find the equation of a line you need a point \((a,b)\) and the gradient \(m\). This determines the gradient of the required line. Use B\((6,3)\) and \(m\). The perpendicular bisector ...
Perpendicular lines will always cross at right angles. To determine if two lines are perpendicular, we need to multiply their gradients together. If the lines are perpendicular to each other ...
Constructing a line perpendicular to a given line and through a point not on the line is one of the most important constructions ...
Find the slopes of those tangent lines. Find the equation of those ... to \(C\) and are also perpendicular to \(L\text{.}\) ...
