Knowing these basic rules about circles and tangent lines, you can determine the basic elements of a circle, calculate the number of points of intersection, external tangent, and internal tangent of two circles, and find the value of the given parts. radius and tangent section.Tangent and Secant Properties of a Circle: A circle is the set of all points in a plane at a constant distance from a point. The fixed point is known as the center, and the maximum distance is the radius of the circle. A line joining a circle at two different points is called a secant of the circle.

A line that meets the circle at only one point is called tangent to the circle at that point. In this article, we will talk about the relative positions of circles and lines in the same plane. We will also investigate the existence of tangents to a circle and their properties.

A circle is a point that moves in a plane so that its distance from a fixed point in the same plane remains constant.

Tangent And Secant Of A Circle Problems

As you can see in the diagram, (O) is the fixed point called the center and (OA,) or (OB) is the fixed distance called the radius of the circle. (CD) is the base of the circle, and (AB) is the diameter, which is the longest. The area enclosed by the two radii (OP) and (OQ) and the arc (PQ) is called the area, and the area enclosed by the arc (PQ) and the arc (PQ ) ) is. this is called a part.

A line that intersects the circle in two different places is the segment of the circle. In the given diagram (AB) is the area of ​​the circle.

Tangent: A line joining a circle at only one point is called a tangent to the circle. In the given diagram, the line (AB) is perpendicular to the circle at (P.)

Point of contact: The point (P,) where the tangent to the circle meets the circle, is called the point of contact of the tangent. In the given diagram, (AB) touches the circle at (P.) Therefore, (P) is the point of contact of the tangent.

On a motorized bicycle, the wheels move in a line tangent to the circle. The spokes of the wheels have spokes, each of them speaks through the contact point of the wheel, and the ground is in the line where the wheel moves. The property of tangent to a circle is established by the following theorem:

Therefore, (OP) is greater than any line segment connecting (O) to any point of (AB,) other than (P.)

But, the shortest distance between a point and a line is the linear distance from the point to the line.

The line perpendicular to the tangent at the point of contact is known as the normal to the circle at the point of control.

Alternate Segment Theorem

Suppose a tangent segment and a segment are drawn to the circle from an external point. Here, the square of the measure of the tangent part is equal to the product of the measure of the part and its external part. They are neutral in the (U.)

We looked at the tangent and secant properties of a circle. We have provided sample solutions along with some FAQs.

Answer: A tangent can touch a circle at only one point of the circle. A tangent does not cross a circle, which means it cannot pass through the circle. The tangent will never meet the circle at the same points. The tangent line is equal to the radius of the circle.

Q.5. What do you mean by a tangent to a circle? Answer: A tangent to a circle is a straight line that touches the circle at only one point.

We hope this detailed article about tangent and scale properties of a circle will help you in your studies. If you have any doubts, questions or suggestions regarding this article, feel free to ask us in the comment section and we will be happy to help you. Happy reading! How are you! Today we will explore what can happen when a circle and a line or two lines meet. Let’s start by defining the vocabulary we need. A line on a circle that touches two points outside the circle is a segment of the circle.

Segments Of Tangents, Secants, And Chords

Here is an example of this. We can see that the line meets the outside of the circle at two points and creates a line segment between these points, shown in red. This part of the line is called the maximum.

Now our two points create an angle inscribed in our circle, which we label with the symbol (x) and the degree symbol. From the corner there is a part of the circle between the points where the points join the circle, highlighted in yellow. This is the broken bow. We can find the measure of our angle written as (x) if we know the length of the intercepted arc in degrees. An interrupted arc is the same measure as a central angle that uses the same two points as an inscribed angle, but whose extremity is at the center of the circle.
