Answer:
Hello everyone this is (your name), I'm from (Your grade and Section) and I'm here to report about the secant and tangent of the circle.
WHAT IS CIRCLE?
a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
WHAT IS THE CENTRE OF A CIRCLE?
In geometry, a centre or center of an object is a point in some sense in the middle of the object. According to the specific definition of centre taken into consideration, an object might have no centre.
WHAT IS THE RADIUS OF A CIRCLE?
Radius of a circle is the distance from the center of the circle to any point on it's circumference. It is usually denoted by 'R' or 'r'. This quantity has importance in almost all circle-related formulas. The area and circumference of a circle are also measured in terms of radius.
WHAT IS THE DIAMETER OF A CIRCLE?
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
WHAT IS THE CHORD OF A CIRCLE?
A chord of a circle is a straight line that connects any two points located on the circumference. If the chord passes through the center of the circle, then it is called a diameter. A diameter divides the circle into two equal parts. The segment that represents half the length of a diameter is called the radius.
WHAT IS THE ARC, MINOR, MAJOR, AND SEMI ARC OF THE CIRCLE?
A semi-circle is associated with half of a rotation which is 180°. Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°. Major arcs are associated with more than half of a rotation, so major arcs are associated with angles greated than 180°. In the Main Meaning, The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that could be drawn by connecting the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle, it is known as a semicircular arc.
WHAT IS THE SECTOR OF A CIRCLE?
A sector of a circle is formed when a circle is divided using two radii. Each sector has an angle between the two radii. The sector with an angle less than 180 180 degrees is called a minor sector and the sector with an angle greater than 180 degrees is called a major sector.
WHAT IS THE MINOR, AND MAJOR SEGMENT OF A CIRCLE?
A segment of a circle can be defined as the region which is created by a secant or a chord with the corresponding arc of the circle. The segment portraying a larger area is known as the major segment and the segment having a smaller area is known as a minor segment.
WHAT IS TANGENT OF A CIRCLE
In Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs.
WHAT IS SECANT OF A CIRCLE?
A secant is an extension of a chord in a circle which is a straight line segment of which the endpoints lie on the circle.
WHAT IS THE DIFFERENCE BETWEEN THE TANGENT AND THE SECANT OF A CIRCLE?
In a secant, the line intersects the circle at two points. But a tangent intersects the circle at only one point around its outer line. This is the basic difference between a secant and a tangent. But the common fact between them is both the lines are drawn from outside of the circle.
WHAT IS THE FORMULA OF CROSS TANGENT OR BISECTOR THEOREM?
[tex]T = \frac{1}{2} (a + b)[/tex]
t = tangency angle
a = Major arc
b = Minor arc
WHAT IS THE FORMULA OF ISOSCELES TANGENT ANGLE?
[tex]S = \frac{1}{2} (a - b)[/tex]
s = secancy angle
a = Major arc
b = Minor arc see
WHAT IS AREA OF THE CIRCLE?
[tex]A = πr²[/tex]
A = Area of the circle
Alpha sign = Central angle
π = 3.14
r = radius
WHAT IS THE DIAMETER OF THE CIRCLE?
[tex]d = 2r[/tex]
d = diameter
r = radius
WHAT IS THE CIRCUMFERENCE OF THE CIRCLE?
[tex]C = πd = 2πr[/tex]
C = Circumference or distance
d = diameter
r = radius
π = 3.14
WHAT IS THE FORMULA OF THE SECTOR?
[tex]A = \frac{ \alpha }{360} πr²[/tex]
A = Area of the circle given by the central angle
Alpha sign = Central angle
r = radius
π = 3.14
WHAT IS THE FORMULA OF THE ARC LENGTH?
[tex]C = \frac{ \alpha }{360} πd = \frac{ \alpha }{360} 2πr[/tex]
C = Length of the arc
π = 3.14
d = diameter
r = radius
Alpha sign = Central angle
WHAT IS INSCRIBED ANGLE?
In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle. Equivalently, an inscribed angle is defined by two chords of the circle sharing an endpoint.
WHAT IS THE FORMULA OF INSCRIBED TO CENTRAL ANGLE?
[tex]I = 2C[/tex]
[tex]C = \frac{1}{2} I[/tex]
I = Inscribed angle
C = Central angle
