1.
(a) To develop reasoning power of the students.
(b) To
enhance efficiency of the students in application of the Geometry.
(c) To
develop the capability of problem solving in different field of life.
Specific Objectives / Desired Learning Objectives
2. After this lesson
students will be able to:-
- Define a circle
- Define the
elements of the circle
- Draw a circle and
labels its elements
Previous Knowledge
3. Students have the basic idea of Geometrical
shape. They can also identify, nominate, and define basic elements of Geometry.

4. Black/ White board,
Chalk/ Board marker, Duster, Pointer, Pictures, Models and Charts. Tests
(Activity).
Introduction
5. Dear students! Be
attentive and look at these pictures, Models and things carefully. (show
pictures, Models and things of different geometrical shapes to students and
then ask the following questions by pointing out the students)
Q-1. What is
shown in this picture?
Q-2. What is the
shape of the full moon, wheel, bangle, ring or CD?
Q-3. What do we
call these shapes in Geometry?
Okay! Your views are good
and you explained nicely.
Students likewise our
today’s lesson is CIRCLE.
Statement of Aim
6. Students, In this lesson we shall discuss about the Circle, its five
elements and few examples related to this topic.

CIRCLE Definition 1.
Points whose distance from fixed point remains constant. Elements of the Circle 2.

Q1.
What is meant by Circle? Ans. The shape traceable on a plane by a point moving in such a way that its distance from a fixes point on the same plane remains constant is called a circle.  Q2. What is the centre of
the circle? Ans. The fixed point on a
plane by which the distance of moving point remains constant is called centre
of the circle. As in the figure centre of the circle = O Q3. What is the Radius of
the circle? Ans. Distance of moving
point from fixed point on the plane is called radius. As OC= r = SR/2 Q4. What is chord of the
circle? Ans. A line segment having
end points on the circle. As in the circle Chord = PQ Q5. What is diameter of the
circle? Ans. A chord that passes
through the centre of the circle is called its diameter. As in the
circle, CD = SR = 2r Q6. What is the
circumference of the circle? Ans. The perimeter of the
circle is called circumference of the circle. Circumference = PSRQDSP =
2 π r The
ratio of circumference of a circle and its diameter is constant and is
denoted by Greek letter, π (pie). π =
Circumference / Diameter π =
C /D C
= D, we know that D = 2r So, C = 2 π r , where
“r” is the radius of the circle and
π = 22/7 = 3.1416 approx |

Recapitulation
14. Go over the main
points of the lesson.
Consolidation
8. Invite the students
for asking questions and then ask the following questions from the class.
- What is meant by
circle?
- What are the
elements of the circle?
- What is the
diameter of the circle?
- What do we mean by
circumference of the circle?
Activity
Describe the diagram of
the circle and then write down the elements of the circle. Also solve simple
numerical problem.
Home work
9. Draw the shapes of the
circle in your note book having radius = 2cm, 3cm, 4cm, 5cm, and 6cm and label
their elements.
Conclusion
10. Dear students! This was all about today’s topic. In the next
period, we shall discuss about Triangle.
