Help your students prepare for their Maths GCSE with this free equation of a tangent to a circle worksheet of 30 + questions and answers
The tangent to a circle is a straight line that touches a curve at a single point. The distance from the centre of the circle (sometimes referred to a centre O) to the circumference of the circle is called the radius.
The radius of the circle and the tangent are perpendicular lines as they meet at a right angle. In order to find the equation of the tangent you need to find the gradient of the tangent which can be calculated by working out the reciprocal of the gradient of the line that intersects it at a right angle (the gradient of the radius).
Then you need to find the y intercept by substituting in the coordinates of the point where the tangent and radius intersect.
Looking forward, students can then progress to additional number worksheets, for example a Area and circumference of a circle worksheet or a Circles, Arcs And Sectors worksheet.
