Equation of a circle at a glance
The general equation of a circle is part of the topic on non-linear equations and graphs in coordinate geometry. Students are expected to recognise the equation of a circle in the form: x²+y²=r², where r is the radius of the circle.
The general equation of the circle in centre-radius form, (x+a)²+(y+b)²=r², is not examined at GCSE; the centre of the circle will always be the origin when the circle graph is plotted on the xy coordinate plane.
Students may be asked to find the coordinates of the point(s) where the circle crosses an axis. For example, to find the point(s) where the circle x²+y²=9 crosses the y-axis, substitute x=0 into the equation of the circle, then solve the resulting quadratic equation.
A tangent to a circle is a straight line that touches the circle at one point. The tangent is perpendicular to the radius of the circle. To find the equation of the tangent at this point, first find the gradient of the radius, then use this to find the gradient of the tangent. Finally, find the equation of the tangent using its gradient and the known point on the circumference, and write in the standard form y=mx+c.
Looking forward, students can then progress to additional circles, sectors and arcs worksheets and other geometry worksheets, for example an angles in polygons worksheet or area and circumference of a circle worksheet.
