RD Sharma Class 10 Chapter-10 Circles revolves around two theorems related to a tangent. The first theorem states that when you draw a tangent at any point of a circle, then it will become perpendicular to the radius at the common point. Develop an in-depth understanding of this theorem by practicing questions from the first exercise.
According to the second theorem, when we draw a couple of tangents from an external point to a circle, then they both are equal. To master this theorem, you will find a lot of questions to build your understanding level in the second exercise of Chapter-10 RD Sharma Class 10 textbook.
Fill in the blanks:
(i) The common point of a tangent and the circle is called………… .
(ii) A circle may have ………… parallel tangents.
(iii) A tangent to a circle intersects it in ……… points(s).
(iv) A line intersecting a circle in two points is called a ………… .
(v) The angle between tangent at a point on a circle and the radius through the point is ………… .

Theorem 1: A tangent drawn at any point of the circle is said to be perpendicular to the radius at their meeting point.
Theorem 2: A pair of tangents drawn from an external point to a circle are said to be equal in length.
