Circles
1.Parts of a circle
A circle is a shut curve in a plane such that whole points on the curve are equidistant from a primed(p) point.
The given distance is called the radius of the circle.
A chord is a line segment with its end points on the circle and a diameter is a chord passing through the centre.
An dismissal is a part of the circle.
A segment is the region jump by a chord and an arc of the circle.
A domain is the region bounded by two radii and an arc.
2.Chords of a circle
next are properties on chords of a circle. All these facts can be proved by the properties of congruent triangles.
|Theorem |Example |
| |O is the centre of the circle. Find the unknown in each of the |
|Theorem 1 |following figures. |
