LESSON
C. DISCUSSING THE PARTS OF A CIRCLE
CONCEPTS AND
PRACTICING NEW SKILLS A circle is the set of all points on a plane at a given distance from a fixed point
called the center. A circle is named by its center, Ex. ʘ A.
A Center is the point. Every point on the circle is at the same distance from the
center.
A radius (plural, radii) is any segment joining the center to a point on the circle.
A chord is a segment joining any two points on the circle.
A diameter is a chord passing through the center.
An arc is a part of a circle between two points on the circle.
A semicircle is one half of a circle and measures 1800. A diameter divides the
circle into two semicircles.
A central angle of a circle is an angle whose vertex is the center of the circle and
whose sides are radii of the circle.
A Secant is a line that intersects a circle in two points
A Tangent is a line in the plane of a circle that intersects the circle in exactly one
point.
A Point of tangency is the point where a tangent line touches the circle
D. ACTIVITY (Learners will be given the different parts of a circle with its
definition. And while describing its parts, learners will be given
chances to draw and illustrate the given parts on the board.)
(At the same time, learners will be taught how to name the given parts of a
circle.)
E. ANALYSIS 1. How did you identify the radius, diameter, and chord of a circle?
2. How did you name chords, arcs and angles of a circle?
3. Do you think there is a relationship between the radius and diameter? If yes, what is it?
H. ASSESSMENT/ Direction: Label the figure below. Identify and name the following:
1. radius
EVALUATION
2. diameter
3. chord
4. semicircle
5. minor arcs
6. major arcs
7. central angles
8. inscribed angles
