Measurement and Geometry : Module 26 Years : PDF Version of module. Most geometry so far has involved triangles and quadrilaterals, which are formed by intervals on lines, and we turn now to the geometry of circles. Tangents are introduced in this module, and later tangents become the basis of differentiation in calculus. The theorems of circle geometry are not intuitively obvious to the student, in fact most people are quite surprised by the results when they first see them.
Circle Notes Pdf. At the top of the circle we begin on the note C. The two parallel chord of a circle are 10 and 12 cm and the radius of the circle is 13 cm. The area enclosed between the two concentric circles is cm2. Note: i Necessary and sufficient condition for general equation of degree 2 i. The pitch circle is an imaginary circle that contacts the pitch circle of any other gear with which it is in mesh. Here you can download a copy of the unit circle.

In Euclidean plane geometry , a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems , and play an important role in many geometrical constructions and proofs. Since the tangent line to a circle at a point P is perpendicular to the radius to that point, theorems involving tangent lines often involve radial lines and orthogonal circles. A tangent line t to a circle C intersects the circle at a single point T. For comparison, secant lines intersect a circle at two points, whereas another line may not intersect a circle at all.

Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It only takes a minute to sign up. But are there other ways? Here are a few other ways to find the tangent lines via more or less direct computation. They might be overkill when working with circles, but these methods generalize to other types of conics. The general problem can be transformed into this one via translation, scaling and rotation, so the solution to the general problem can be obtained by transforming these lines back into the original coordinate system. So, to convert the unit circle tangent lines into the original coordinate system, apply the three transformations in reverse order, i.
