How many circle theorums are there?

Answer 1

7 circle theorums

1 the angles between a tangent and a radius is 90 degrees

2 the angle at the origin is double the angle at the circumfrence

3 the oppsite angles in a cyclic quadrilateral add up to 180 degrees

4 the angle of a trianle in a semi circle is 90 degrees

5 the alternate angles subtended at a segment are the same

6 the tangents are the same length from the same point of origin.

7 the alternate angle at a tangent and a triangle is the same.
