WebThe lines are called secants (a line that cuts a circle at two points). This also works if one or both are tangents (a line that just touches a circle at one point), but since two lengths are identical we don't write c×d or c×c we just write c 2: ...

WebThere are two circle theorems involving tangents. 1. The angle between a tangent and a radius is 90°. 2. Tangents which meet at the same point are equal in length. Example … WebSep 4, 2024 · A tangent to a circle is a line which intersects the circle in exactly one point. In Figure 1 line A B ↔ is a tangent, intersecting circle O just at point P. Figure 1. A B ↔ is tangent to circle O at point P. A tangent has the following important property: Theorem 7.3. 1 A tangent is perpendicular to the radius drawn to the point of intersection.
WebBy definition a tangent must be perpendicular to a radius Alternatively you can think of a tangent as a chord that extends beyond the circle, but has zero length inside the circle. Then the line from the centre of the circle (the radius) must be perpendicular to the tangent, as proved in the previous theorem.
