III. Learning Experiences
A. Preparatory Activities
a. Have the pupils identify which of these is a circle.
a. When can we say that a figure is a polygon?
Ask the pupils: “Is Circle a polygon? Why? Why not?
B. Developmental Activities
a. Have the pupils observe the circles below.
Take a look at each of the circles. Do you find any line segment?
b. Use circle zero to complete the following statements:
1. The distance from point O to point F is ______.
2. The distance from point O to point M is ______.
3. The distance from Point O to point G is ______.
4. If point G, O, and F lie on one line, the distance from point G to
point F is _______.
c. Have the pupils observed the circle. Introduce the Radius and
Diameter of a circle. Show examples of radius that are connected to the
tangent and from a center. Use compass in drawing a circle.
A circle is a closed plane figure that is not made up of line
segments, so it is not a polygon. A circle named by its center.

1. Refer to circle O. Explain why OP AND OQ do not form a diameter.
Use circle O to answer the following.
a. Name two diameters:
c. Name six radii
1. 2. 3. 4. 5. 6.
A circle is a set of all points in a plane that are at a fixed distance from a point called center.
A radius is a line segment from the center to a point on the circle.
A diameter is a line segment which passes through the center of a circle and whose endpoints are
on the circle.
The length of radius is one-half the length of a diameter of a circle.
A compass is an instrument used to draw circles.
Use a real compass or an improvised one to draw circles with these given radii.
1. 1 cm
2. 1.5 cm
3. 2.5 cm
4. 6 cm
5. 7 inches
