The chapter helps you to form the base for geometry. Euclidean geometry is based on axioms and theorems to find out relations between lines, figures and angles in space. It presents a student with a deductive, comprehensive, and logical approach. You can develop the basics required to progress further into the intricate and intriguing world of geometry. Angles in a geometric figure form various relations with each other.
Chapter 8 is all about these relations. Concepts of vertically opposite, complementary and supplementary angles are presented here with clarity. Here, you are introduced to the various types of triangles and the properties of their three angles. You learn how to figure out the values of unknown angles in a geometry composed by triangles.
Properties like exterior angles, linear pairs, vertically opposite angles, alternate angles, etc. Suppose you see two similar objects and state to a friend that the two are geometrically same. But your friend refuses to believe so. How do you prove it? Studying congruency of triangles provides with an insight on how you can do so. Here, you build the logic to prove that two triangular 2D bodies are a replica of each other, using Euclidean theorems.
Named after Rene Descartes, this branch of mathematics that combines geometry with algebra is called Cartesian coordinate geometry.
Plotting points in planes with its coordinates and notations is an essential concept covered in this chapter. Line equations and Apollonius theorems are included as well. Useful in finding out the area of any triangle where only the length of its sides is given, Herons formula is an essential tool to learn. Further, the chapter discusses the application of this formula to find areas of quadrilaterals. With the concept of the equation of a straight line, one can solve many other simple real-life problems.
Linear equations are an essential tool to do the same. In this chapter, a student learns to present the geometric representation of various straight line equations. A quadrilateral is a polygon with four edges and four vertices. Here, you learn about the various properties of a quadrilateral and the relation between its angles. After developing the concept of convex and concave triangles, you get to solve problems involving a variety of quadrilaterals with unknown values of edges.
Formulae of area and volumes of different quadrilaterals are also introduced here. This chapter covers the formulae and methods of calculating the areas of various triangles and other parallelograms like rhombus and trapezium.
One also learns their application by solving problems involving circles with other inscribed geometrical figures.
In this chapter, you acquire the skills to construct geometric figures only using a scale and a compass. You learn to construct various angles, bisect lines, inscribe triangles into figures and do much more. An easy yet scoring chapter, practising the problems here can lead you to get better grades tomorrow. A right circular cylinder is a commonly occurring geometrical figure in many other areas of science like physics and biology.
So, you need to learn the ways of measuring its dimensions. That is what you learn in this chapter. Here, a student learns to solve problems involving volume and surface area of a right circular cone. Learning the formulas for volumes of spheres is a part of the entire curriculum. The chapter falls under the topic of analytical geometry.
Statistics is the science of collection, presentation, analysis and interpretation of numerical data. Here, you are introduced to the basic concepts like primary and secondary data, discrete and continuous frequency distribution, etc. They offer a visual representation of statistical data. In this chapter, you learn about the different measures of central tendencies such as the mean, median and mode. With these measures, you can identify the location of maximum number values in a distribution.
Here, one understands the essential concepts like different types of events mutually exclusive, complementary, equally likely, etc. One also learns the theorems of compound probability, and other axioms and their application in solving complex problems.
