TOPIC [For Complete Explanation] |
1 |
Introduction Circle, triangle quadrilateral and other polygons are two dimensional figures. So these figures are called plane figures. In this chapter we will discuss the area related the plane figures and combinations of plane figures. First of all teacher will define all the terms which are related with the circle, like definitions of Circle, centre of the
circle, radius, diameter, chord, segment, sector, minor segment, major
segment, minor sector, major sector, semicircle, quadrant and circumference
of the circle. |
2 |
Circumference and perimeter Now teacher will explain different properties of circle to the students and explain the difference between the circumference and perimeter of the circle. Length of curved surface is called circumference and length of the boundary is called perimeter. In case of circle circumference and perimeter both are same. But in semi-circle both are different. |
3 |
Now teacher will explain the formula and method of finding the circumference and perimeter of the circle, semi-circle and quadrant. Circumference of semi-circle = 𝞹r Perimeter of semi-circle = 𝞹r + 2r Perimeter of quadrant of circle = (1/2)𝞹r + 2r |
4 |
Area of Segment and Sector Now teacher will explain the formula and method of finding the area of the circle,
semi-circle, quadrant, minor segment, major segment, minor sector, major
sector all with central angle 60o, 90o, 120o Also help the students in the implementations of all these
formulas. Area of circle Area of minor sector Area of major sector = Area of minor segment = Area of major segment = Area of Quadrant =
|
5 |
Now explain the area related to different types of
triangles and their implementations in different problems. Area of triangle, right angled triangle, equilateral triangle and scalene triangle. Area
of triangle = Area
of equilateral triangle = |
6 |
Area of Quadrilaterals Now teacher will explain the area related to different types of quadrilaterals and their implementations in different problems. Area of trapezium, parallelogram, rectangle, rhombus and square. Area of quadrilateral = Area of parallelogram = Area of rectangle = Area of rhombus = Area of square = |
7 |
Now teacher will introduce the topic combination of
different plane figures and explain the topic by taking different examples. |
8 |
Angle made by minute and hour hand of the watch. Here teacher will explain the angle made by minute hand in one minute = 6o and angle made by hour hand in one minute = ( ½)o Teacher will also explain the topic by taking some examples |
9 |
Regular Hexagon Teacher will explain
the concept of regular hexagon and method of finding its area. A regular hexagon can be divided into six equilateral triangles. So Area of
regular hexagon = 6 X Area of equilateral triangle. |
EXCELLENT WEBSITE . ITS VERY HELPFULL FOR TEACHING
