Question

Terms related to circle Segments, sector, any two theorems based on your interest from circles​

Answer 1

Answer:

First circle theorem - angles at the centre and at the circumference. Second circle theorem - angle in a semicircle. Third circle theorem - angles in the same segment. Fourth circle theorem - angles in a cyclic quadlateral.

Answer 2

Answer:

It is a little easier to see this in the diagram on the right. Each chord is cut into two segments at the point of where they intersect. One chord is cut into two line segments A and B. The other into the segments C and D.

This theorem states that A×B is always equal to C×D no matter where the chords are.

In the figure below, drag the orange dots around to reposition the chords. As long as they intersect inside the circle, you can see from the calculations that the theorem is always true. The two products are always the same.

( Because the lengths are rounded off for clarity, the calculations will be slightly off if you enter the displayed values into your calculator).
