In this chapter students will be introduced to the concept of Cartesian system, plotting a point in the plane if its coordinates are given.
Make yourself aware of X and Y axis and plot a point using a graph. There are 5 exercises in this chapter including the summary.
In this chapter, students will understand what is a linear equation, solving linear equations, graphical representation of linear equation in two variables, equations of lines parallel to the x-axis, and y-axis. Like other chapters there are 5 exercises including the summary exercise. Attempt all the questions for knowing your practice, and consult our book in case you need any help. Solve the exercises, know about the postulates of Euclid for grasping the chapter in a better way.
And yes for any kind of difficulty refer our book containing solutions of all exercises. Chapter 6: Lines and Angles In chapter 5 students understood that minimum two points are needed to draw a line, they also became aware of some axioms. Now, this chapter introduces students to the basic terms and definition of line and angles.
Students will learn about intersecting and non-intersecting lines, pair of angles, transversal and parallel lines, lines parallel to the same line, and finally the angle sum property of a triangle. And like previous chapters, this chapter also ends up with exercises.
Chapter 7: Triangles In your previous classes you learnt about triangles and their properties and in chapter 6 you understood about some triangle properties. Students will learn about the congruence of triangles, criteria for congruence of triangles, properties of a triangle, and inequalities in a triangle in this chapter.
Congruent triangles are those triangles who are equal in size or you can say replica of each other. Learn more about congruent triangles and solve the exercises at the end. Chapter 8: Quadrilaterals In previous chapters students learnt about triangles which have three angles.
Now add one more angle in the figure and see what comes up. A quadrilateral has 4 angles. Here, students will learn about the angle sum property of quadrilaterals, different type of quadrilaterals, properties of a parallelogram, conditions that make a quadrilateral parallelogram.
Finally, students will be introduced to the concept of the mid-point theorem. So learn the new concepts and take our help in case you stuck somewhere. Chapter 9: Areas of parallelogram and triangles In this chapter, students will learn about figures having the same base and between the same parallels, parallelograms on the same base and between the same parallels, triangles on the same base and between the same parallels.
Also learn about trapezium. There are 4 exercises in this chapter. Solve each of them, initially you may find them difficult, but try to attempt them by yourself and take guidance of our book in case of any doubt. Chapter Circles Here students will learn what is a circle and its related terms, the angle of a chord at a point, perpendicular from the center to a chord, circle through three points, equal chords and their distance from the center, the angle subtended by the arc of a circle, and cyclic quadrilaterals.
There are 2 theorems in this chapter related to chords.
Go through theses theorems and learn how to prove them. Refer our solved book in case you face any difficulty.
Chapter Construction In previous chapters, you came across triangles. But those triangles were not made with precision. As those were for your understanding purpose only. Now in this chapter, students will learn about the basics of construction, and work with some construction on triangles.
Know how to measure angle with protector, how to draw perpendicular and how to use the compass. You may find this chapter interesting, if you get correct knowledge of construction. Solve the exercises at the end. You know how to calculate perimeters and area.
Now in this chapter calculate the area with a different formula.
