4. Questions:
1.How many sides are
there in the figure?
2. Is this a polygon?
3. What do you think
this figure called?
7. OBJECTIVES
At the end of the lesson, the students are expected to
get 75% proficiency of the following:
a. Illustrate a circle and the terms related to it: radius,
diameter chord, center, arc, chord, central angle, and
inscribed angle.
b. Appreciate the importance of a circle and develop
cooperation within the group, and
c. Draw parts of the circles and solve a problem on circle
8. DEFINITION OF A CIRCLE
Note: A circle is named by its center.
Circle is the set of all points that
are the same distance from a
fixed point.
9. PARTS OF A CIRCLE
1. CENTER- The given point from which all
points on a circle are the same distance.
2. CIRCUMFERENCE- The distance around
the edge of a circle.
3. RADIUS- Distance from the center to any
point of circumference.
10. PARTS OF A CIRCLE
5. CHORD- A line segment whose endpoints
are on the circle.
4. DIAMETER- It is chord that passes through the
center of a circle. It is the longest chord of a circle and it
is twice the length of the radius of a circle.
6. SECANT- A line that intersects the circle in
two different points.
11. PARTS OF A CIRCLE
7. TANGENT- A line which touches a circle at
just one point.
8. ARC- It is a portion of the circumference of
a circle.
9. SECTOR- A circular sector or circle sector (symbol:
⌔), is the portion of a disk enclosed by two radii and an
arc.
12. PARTS OF A CIRCLE
10. SEGMENT- The segment of a circle is the
region bounded by a chord and the arc.
11. CENTRAL ANGLE- It is an angle that forms
when two radii meet at the center of a circle
12. INSCRIBED ANGLE- It is an angle formed by
two chords in a circle which have a common endpoint
13. NAME THE PARTS OF THE
CIRCLE
