A straight line which intersects a circle at two distinct points is called a secant. A straight line that touches a circle at only one point is called a tangent.
A straight line which intersects a circle at two distinct points is called a secant. A straight line that touches a circle at only one point is called a tangent.
Either of the points, B or C on the circumference of the circle can moved in this geogebra applet to discuss tangent, secant and chord.
Either of the points, B or C on the circumference of the circle can moved in this geogebra applet to discuss tangent, secant and chord, and some of their properties.
