Number of Tangents from a Point on a Circle Class 10: Theorem 10.2 & Examples

A student-friendly guide for CBSE Class 10 on how many tangents can be drawn from a point to a circle — none from an inside point, one from a point on the circle, and exactly two from an outside point — plus the length of a tangent and Theorem 10.2 (the two tangents from an external point are equal in length), with worked examples.

Tangent and Secant of a Circle Class 10: Meaning, Difference & Examples

A student-friendly guide to how a line and a circle can meet in CBSE Class 10 — the three cases (non-intersecting line, secant, tangent), what a secant and a tangent are, the difference between them, the point of contact, and simple examples that decide the case from the distance to the centre.

Tangent to a Circle Class 10: Theorem, Proof & Examples (Tangent ⊥ Radius)

A student-friendly guide to the tangent to a circle for CBSE Class 10 — what a tangent and point of contact are, Theorem 10.1 (the tangent at any point is perpendicular to the radius through the point of contact), a clean proof, and worked examples that use the resulting right angle with the Pythagoras theorem.
