RS Aggarwal Solutions Class 10 Maths Chapter 12 Circles: If you are a Class 10th student, this blog is for you. In this blog, we will mainly talk about the RS Aggarwal Solutions Class 10 Maths Chapter 12 Circles. The RS Aggarwal Solutions Class 10 Maths series is designed by subject matter experts to help Class 10 students with their maths exams.
The chapter Circles deal with the tangent to a circle, the number of tangents from a point on a circle, length of a tangent. After solving this chapter students will the meaning of a tangent to a circle, the tangent to a circle is perpendicular to the radius through the point of contact, and the lengths of the two tangents from an external point to a circle are equal.

RS Aggarwal Solutions Class 10 Maths Chapter 12 Circles – Overview
In Chapter 12 of RS Aggarwal Solutions Class 10 Maths, you will learn about the different features of circles and geometric figures associated with them. You will also learn about the features of radius, diameter, chord, tangent, normal, and concentric circles and how to solve problems using the same concepts.
There are 2 exercises in this chapter and all the questions will be based on the concept of circles.
- In the first exercise, you will be asked to calculate the length of radius, tangents, chords, normal, etc. You will have to construct a line or join two points in the same diagram to solve the problem easily.
- In the second exercise, a strong foundation for the chapter is required. You will have to learn how to construct something extra to match the theorems you have learned previously and correlate the given diagram to find the answers.
What Exactly is a circle?
A circle is a two-dimensional shape created by a set of points in the plane that are separated by a constant or fixed distance (radius). The fixed point is the origin, or center, of the circle, and the radius is the fixed distance between the points from the origin.
Parts of a Circle
The following are the main components of a circle:
-
Circumference: The circumference of a circle, also known as the perimeter of a circle, is the distance around the circle’s perimeter.
-
Radius: A circle’s radius is the distance between its center and any point on its circumference. A circle has numerous radii because they are the distance from the center and touch the circle’s perimeter at different locations.
-
Diameter: A diameter is a straight line that links two points on the circle’s periphery and passes through its center. It’s important to remember that the circle might have numerous diameters, but they must all:
-
go straight through the middle
-
be made up of straight lines
-
At two locations, touch the circle’s boundary.
-
Cord: Any line segment touching the circle at two different locations on its perimeter is called a chord of circles.
-
Tangent: A tangent of a circle is a line that intersects the circle at a single point.
-
Secant: In circles, a secant is a line that crosses two points on an arc/circumference of a circle.
-
Arc: A curve is a segment or portion of a circle’s circumference that is referred to as an arc of a circle.
-
Segment: A segment in a circle is defined as the area enclosed by the chord and the associated arc in a circle. Minor segments and significant segments are the two sorts of segments.
-
Sector: The region contained by two radii and the associated arc in a circle is referred to as the sector of a circle.
