another quest ko to ah kayo talaga eh pero maganda naman yung answer ng isa kaso may kulang. kaya gumawa ako another quest :) I don't know how to draw it but I know now kaso Lang meron pa akong hindi alam :(

Answer:
answer at the picture :)
p1 = The figure, use a protractor or any circle object to make a circle :) now copy these
p2 = The answers
Explanation:
so, A circle in this lesson is the set of all p0ints in a plane at a given distance (called radius) from a given p0int (the center) in the plane. it is named by its center (The center is Y so the name of the circle is "Y")
A radius of the circle is a line segments from the center to any p0int of the circle:
Ex: __
YG
A chord of the circle is a line segment whose endp0ints lie on the circle (or circumference)
Ex: ___ __
GO, JZ
A diameter of the circle is a CHORD containing to the center (or a diameter was made by 2 radius)
Ex: ___
GO
why diameter is a chord? because a diameter has 2 end p0int. but what's the difference? So, diameter is a chord, a chord that contains the circle.
So Now let's talk about *Arcs*
A semicircle is a half of a circle or is an arc of a circle whose end p0ints are the p0ints of the diameter
A minor arc is an arc of a circle that is smaller than a semicircle or smaller than a half
A major arc is an arc of a circle that is bigger than a semicircle or larger than a half
then let's talk about *Angles*
A central angle is an angle whose vertex (or middle) is the center of the circle
Ex:
∠JYG, ∠GYO
An Inscribed angle is an angle whose vertex is on the circle and whose sides contain chords of the circle
Ex: ZJU
and let's talk about *lines*
a secant line of a circle is a line that intersects the circle in two p0ints
Ex:
<-->
OU
a tangent line of a circle is A line lying on the same plane that intersects the circle in exactly one p0int
Ex:
Line i
and p0int of tagency (the p0int of tagent line)
Ex: G

I work hard for this :)
