Circles Flashcards
A circle divides the plane on how many parts and which are these parts
A circle divides a plane on which it lies into three parts they are inside of the circle which is also called the interior of the circle the circle and outside the circle
What is the diameter of a circle
The cord which passes through the centre of the circle is called the diameter of a circle
What is Chord
A line segment which connects any two point is called a chord
What is an Arc
A piece of circle between two points is called an arc
What is major ARC and minor arc
The longest Arc is called the major ARC and the shorter one is called minor Arc
What is Semi circle
An Arc is a semi circle when its end are the ends of a diameter
What is the circumference of a circle
The length of the complete circle is called its circumference
What is a segment
The region between a chord and either of its Arc is called a segment
What is a segment
The region between a chord and either of its Arc is called a segment
What is a sector
The region between an Arc and two radii joining the Centre to the end point of the arc is called a sector
What is a sector
The region between an Arc and two radii joining the Centre to the end point of the arc is called a sector
What is a semi circular region
When two arcs are equal that is each is a semicircle then both segments and both sector become the same and each known as semi circular region
What is a semi circular region
When two arcs are equal that is each is a semicircle then both segments and both sector become the same and each known as semi circular region
