## tangent of a circle example

Example 2 Find the equation of the tangent to the circle x2 + y2 – 2x – 6y – 15 = 0 at the point (5, 6). This lesson will cover a few examples to illustrate the equation of the tangent to a circle in point form. Tangents of circles problem (example 1) Tangents of circles problem (example 2) Tangents of circles problem (example 3) Practice: Tangents of circles problems. And if a line is tangent to a circle, then it is also perpendicular to the radius of the circle at the point of tangency, as Varsity Tutors accurately states. A circle is a set of all points that are equidistant from a fixed point, called the center, and the segment that joins the center of a circle to any point on the circle is called the radius. Tangent to a Circle is a straight line that touches the circle at any one point or only one point to the circle, that point is called tangency. Problem 1: Given a circle with center O.Two Tangent from external point P is drawn to the given circle. Let's try an example where A T ¯ = 5 and T P ↔ = 12. Examples Example 1. 16 = x. Answer:The properties are as follows: 1. We’ll use the point form once again. (4) ∠ACO=90° //tangent line is perpendicular to circle. If two tangents are drawn to a circle from an external point, One tangent line, and only one, can be drawn to any point on the circumference of a circle, and this tangent is perpendicular to the radius through the point of contact. for (var i=0; i
