Class IX Maths - Circles - Theorem Part-III Video By Lets Tute
Video Summary:

In this session on Circles we will be studying three important theorems giving relation between angles, chords and circles. Get a detailed explanation on these theorems in less than 7 minutes:

1) If a line segment joining two points subtends equal angles lying at two other points lying on the same side of the line containing the line segment, then the four points lie on the circle.

2) The sum of a pair of opposite angles of cyclic quadrilateral is 180 degrees.

3) If the sum of a pair of opposite angles of a quadrilateral is 180 degress then the quadrilateral is cyclic.

Understanding these theorems will indeed help you in applying them for solving various problems on Circles.
