4. Introduction
What is a Circle?
A circle is a collection all points in a plane which are
equidistant from a fixed point. The fixed point is called the
Centre and the fixed distance is called the Radius. The
Diameter of a circle is any straight line that passes through
the centre and whose endpoints lie on the Circle
A circle divides the plane on which it lies into three parts.
They are:
1. Inside the circle, which is called Interior of the circle
2. The circle
3. Outside the circle, which is also called Exterior of the
circle
5. What is a Chord?
A Chord of a circle is a straight line segment whose both
endpoints lie on a circle.
If the chord is extended, it is called a Secant. The largest
chord of the circle is a Diameter.
What is a Tangent?
The Tangent is a line that just touches the
circle at only one point. You can draw only 2
tangents from an external point.
What is Point of contact?
Point of contact is the point on the circle where
the Tangent touches
What is a Arc?
A piece of circle between two points is called an
Arc. There are two types of Arc:
i) Major Arc is the Arc which has more length and
ii)Minor Arc For Ex. The
6. What are Slices?
There are 2 main Slices of a Circle
i) Sector
ii) Segment
A pizza slice is a Sector
The slice made by a Chord is the Segment
7. Theorem
1st Theorem
The Tangent at any point of a circle is perpendicular to the
radius through the point of contact.
It means that if a radius is drawn from the point of contact
of the tangent then it is perpendicular to the radius
2nd Theorem
The lengths of tangents drawn from an external point to a
circle are equal.
As you know that we can draw only 2 tangents from an
external point, Hence both the tangents are equal to one
another.
8. Real life examples
There aren’t limited Real Life Examples. So I
am going to show you some of them! 😃
● Vehicle tyres
● Currency coins
● Watches, Wall clocks
● Dart boards
● Human faces
