Today we will discuss about  Sector and Segment of a circle BOYS,WRITE EVERYTHING GIVEN IN THIS BLOG IN YOUR NOTEBOOK. PLEASE DRAW THE CIRCLES AND MARK EVERYTHING GIVEN IN/ON IT. What is Sector of a circle? The sector is basically a portion of a circle which could be defined based on these three points mentioned below: A circular sector is the portion of a disk enclosed by two radii and an arc. A sector divides the circle into two regions namely Major and Minor Sector. The smaller area is known as the Minor Sector whereas the region having Greater area is known as Major Sector . What is Segment of a circle? A segment of a circle can be defined as a region bounded by a chord and a corresponding arc lying between the chord’s endpoints.  To understand the concepts of sector and segment of a circle, watch this video by clicking  on the link 👉  https://youtu.be/viM7a4IUp9Y Let's start Ex-4.6 Q1:  From the figure, identify: (a) the centre o

Good morning students !😊😊 Welcome Back!!   Today, we are going to recall some basic geometrical concepts which you had learnt in your previous classes. At the end of the class, you will be able to: ➤ define and explain the concept of Circle. ➤ identify the different parts of a circle  ➤ illustrate a circle and the terms related to it  : Centre, Radius, Chord & Diameter. ➤  CIRCLE A circle is a shape with all points the same distance from its center. A circle is named by its center. Thus, the circle to the right is called circle A since its center is at  point  A. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. DIAMETER The distance across a circle through the center is called the diameter. A real-world example of diameter is a 9-inch plate.  RADIUS The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two  radii  end-to-end in a circle, you wo

Good morning boys ! Today we are going to learn about QUADRILATERALS. LEARNING OUTCOMES- By the end of the class you will be able to- -name the sides , adjacent sides, oppposite sides ,of a quadrilateral. -name the angles , adjacent angles, opposite angles ,of a quadrilateral. - name the vertices of the quadrilateral. -name the diagonals of the quadrilateral. A quadrilateral is a four sided polygon. It has 4 sides and 4 angles. A quadrilateral can be divided into two triangles. The sum of all angles of a quadrilateral is 360 degrees. A quadrilateral has 4 sides . In the quadrilateral given below , -side AB are opposite to side DC -side AD are opposite to side BC The video given below explains about the diagonals of a quadrilateral. https://www.bing.com/videos/search?g ANGLES  AND SIDES OF A QUADRILATERAL- The video given below explains about the angles and sides  of a quadrilateral. https://www.bing.com/videos/search? The table given below gi

May 08, 2020 GOOD MORNING INTERSECTING LINES If two lines have one common point, they are called  intersecting lines. This common point is called the point of intersection. Have a look at this video to understand even better the concept of intersecting lines https://www.youtube.com/watch?v=ubOyrS7KuXE      Do you observe all the intersections in this picture!!!!! PARALLEL LINES Two lines in a plane that do not intersect each other are said to be  parallel.  There is no point in common between the two parallel lines. Have a look at this video to understand the concept of parallel lines even better.                            https://www.youtube.com/watch?v=HdNCiP5znT8                Check out the parallel sides in each of these given figures which are indicated by the arrows. The opposite sides of the given quadrilaterals are parallel to each other.                                       Do you notice that the tracks are paralle
