Let's explore the key concepts from Chapter 3: Circle in Class 10 Mathematics, Part 2.
This chapter covers various aspects related to circles. Here are some important points:
1. Circle Basics:
- A circle is a two-dimensional figure where all points on its circumference are equidistant from a fixed point called the center.
- The radius of a circle is the segment joining the center to any point on the circle.
2. Tangent and Secant:
- A tangent to a circle is a line that touches the circle at exactly one point (the point of contact).
- A secant is a line that intersects the circle at two distinct points.
3. Inscribed Angle:
- An inscribed angle is an angle formed by two chords (or secants) that intersect at a point on the circle.
- The measure of an inscribed angle is half the measure of the intercepted arc.
4. Intercepted Arc:
- The intercepted arc is the portion of the circle enclosed by an inscribed angle.
- The measure of the intercepted arc is equal to the measure of the inscribed angle.
5. Cyclic Quadrilateral:
- A quadrilateral whose vertices lie on the circumference of a circle is called a cyclic quadrilateral.
- The opposite angles of a cyclic quadrilateral are supplementary.
6. Theorem of Intersecting Chords:
- If two chords intersect inside a circle, the product of the segments of one chord is equal to the product of the segments of the other chord.
Remember, these concepts play a crucial role in understanding circles and their properties. If you have any more questions or need further assistance, feel free to ask! 😊
