In chapter 9 of RD Sharma Solutions, the students will learn about the core concepts of ratio, which form the basics to understand various other mathematical concepts. Chapter 9 - Ratio and Proportion are based on the fact that numbers can be compared by using methods like division. The division method is one of the most efficient ways. The chapter further explains the important terms related to ratio and proportion. Finally, it also teaches the students various questions regarding proportion.
This 10 th chapter in the book deals with the Unitary method. It is the concept that is used to solve practical problems and find the value of the required numbers by finding the value of one article. Chapter 10 - Unitary method helps the students to understand the basic relationship between two commodities and how they affect each other. This chapter forms the basis of work and time questions, time and distance questions, and various other questions based on different topics. Finally, the unitary method is a simple tool that is taught in mathematics, which makes calculations easy.
This chapter comprises the description of the term percentage and its various forms. Chapter 11 - Percentage focuses on the various percentage forms, such as a fraction or a ratio. Students are introduced to few conversion techniques, including converting a fraction and a ratio into their related percent and vice versa.

Students are well aware of the pair of lines and angles. Chapter 14 marks the beginning of geometrical concepts for class 7 th and Lines and Angles, introduce the concepts of the complementary and the supplementary angle to the students. Next, the chapter introduces the students to the different types of angles. The chapter also includes a brief explanation of the varied types of angles formed by a transversal line. Finally, the chapter makes the students practice questions containing unknown angles on a line that helps train students to find unknown angles in triangles, polygons, and quadrilaterals.
This chapter is based upon the geometric figure of triangles. The figure is formed by the intersection of three separate lines inclined towards each other. The essence of Chapter 15- Properties of Triangles is based on the categorisation of triangles. First, these triangles are divided into types depending upon their size and internal angle. Next, the chapter deals with the properties associated with triangles. In the end, the topic focuses on one of the most important theorems, the Pythagoras theorem and its converse along with its triplet.
This is one of the new topics to be introduced in class 7. This chapter comprises the definition and the congruency of different shapes such as squares, rectangles, circles, and triangles. It also introduces the congruence of line segments. Chapter 16-Congruence also includes an important topic (i.e.) the required conditions for the congruence of two triangles. Further, it teaches the students about the congruency of triangles, including the SSS, SAS, ASA, and RHS criterion.
Proceeding with the next chapter in the RD Sharma Solutions or class 7 th , we find that it deals with the methods involved in constructing a shape. Various constructions are a part of the syllabus, and these constructions are done taking into use the compass and the ruler. Chapter 17-Constructions starts with the steps to draw a line segment of the desired measurement parallel to a given line.

In a rectilinear figure, the figure's angles meet at 90° to each other, and this chapter involves the calculation of the areas and perimeter of a two-dimensional rectilinear shape. Every figure has a definitive area and perimeter, which depends upon its dimensions. Therefore, it is used to study the calculations of different geometric figures. The areas are calculated by breaking down the figures into the constituent rectangles and squares and then adding up their data to get to the area of the final figure.
This chapter comprises entirely of the definition of a circle along with the properties of a circle. It concentrates on the chord and the diameter of a circle. Chapter 21-Mensuration II(Area of Circles) also mentions the relationship between the diameter, the radius and list out the formulas to find the area and circumference of the circle. It also includes the types of circles which are useful in higher classes to solve other problems.
