Slice of a circle enclosed between any two radii is called a sector.Semicircle and quadrant are special types of sectors.

Objectives

To understand area enclosed by two radii is sector.

Estimated Time

15 minutes

Prerequisites/Instructions, prior preparations, if any

The students should know a circle, centre, radius,circumference and a sector.
They should know that circle is a planar figure.

Materials/ Resources needed

Non digital: Laptop, geogebra file, projector and a pointer.

Geogebra file: Arcs and Sector of a circle

Download this geogebra file from this link.

Process (How to do the activity)

Move the endpoints of the sector and help them understand the types of sector.

Name all the points on the circumference.
Name the endpoints of the sector.
Name the major and minor sectors.
What can you say about the two straight lines of the sector?

Evaluation

Name the special types of sector?
Give some examples of sector.
