Any point P with coordinates (\(x, y\)) on the circumference of a circle can be joined to the centre (0, 0) by a straight line that forms the hypotenuse of a right angle triangle with sides of length ...

As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...

Calculating the diameter of a circle is one of the most fundamental concepts in geometry. The diameter is an essential component of numerous mathematical equations and real-life applications. In this ...

Understanding how to calculate the radius of a circle is an essential skill in geometry, and it has practical applications in everyday life as well. Whether you are determining the size of a circular ...
