Webon a circle. A diameter is a chord that contains the center of the circle. It is also the longest chord and is equal to twice the length of the radius . A secant is a line that intersects a circle in two points. A tangent is a line, ray or segment in the plane of the circle that intersects a circle in exactly one point, the point of tangency. WebA chord of a circle is a straight line segment whose endpoints both lie on a circular arc.If a chord were to be extended infinitely on both directions into a line, the object is a secant …

Tangent to a Circle: Formulas, Properties, Theorems

WebAn angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc. $ x = \frac 1 2 \cdot \text{ m } \overparen{ABC} $ Note: Like inscribed angles , when the vertex is on the circle itself, the angle formed is half the measure of the intercepted arc. WebA number of interesting theorems arise from the relationships between chords, secant segments, and tangent segments that intersect. First of all, we must define a secant segment. A secant segment is a segment with one endpoint on a circle, one endpoint outside the circle, and one point between these points that intersects the circle. bright horizons broomfield corporate office

Central Angle. A central angle is an angle formed by two radii with the vertex at the center of the circle. Central Angle = Intercepted Arc. In the diagram at the right, ∠AOB is a central angle with an intercepted minor … Web4. Theorem 4: The line that is drawn through the center of the circle to the midpoint of the chords is perpendicular to it.In other words, any line from the center that bisects a chord is perpendicular to the chord.. 5. … bright horizons backup care phone number
