Mathematics Solutions from Chapter -1 - Circles

We have studied that a circle is a collection of all points. In this chapter, we will learn about the existence of the tangents to a circle and study their properties.

This topic discusses the two conditions in which a line touches a circle. This has been explained in detail using activities. It also includes a theorem to prove that a tangent at any point of a circle is perpendicular to the radius.

Mathematics>Geometry>Circles>Tangent to a Circle

This topic explains the tangent to a circle. The word ‘tangent’ was introduced by the Danish mathematician Thomas Fineke. It comes from the Latin word ‘tangere’, which means to touch. It is a line that intersects the circle at only one point.
