How much you can cover 2m, 3m, 5m, 10m, m, 1km, km…? Will it end somewhere? The answer is, No, you can cover as much distance as you want to. There is no end. Now there are two kinds of unknown quantities, one is varying called as a variable while other is constant. In this chapter, you will learn about how a point can be identified in a plane or space.

When we talk about the point in space, we call it 3D geometry. While when we talk about a pint in a plane, we call it as coordinate geometry. But why do need to study this chapter? In order to understand the importance of this chapter, look at this example. If there is a girl standing on the streets, then how you will define her location? We will imagine a map having a north-south direction where the streets will be drawn. After having the reference you can easily point the location of the girl.

Coordinate Geometry has many applications. One famous application is Maps. But here we are talking only about the linear equation in two variables.

NCERT Exemplar Problems Class 9 Maths

After understanding which kind of equations fall under linear equations in two variables, you can now proceed with how we will form the equations from a problem. So assume that there are two kinds of fruits apple and orange. The total number of apples and oranges is But the number of apple and orange is unknown.

Where x is the number of apple and y is the number of oranges. NO win order to find the number of apple and oranges, you need to have one more equation that has the relationship between apple and orange in other words contains x and y. And solve the above equations and thus calculate the number of apples and oranges. Euclid was a Greek mathematician, who has done studies on the geometry.

He has defined point, line, straight line, surface, plane surface.NCERT books are considered the best source to prepare for board as well as competitive exams.

Solution: c We know that, two triangles are congruent, if the sides and angles of one triangle are equal to the corresponding sides and angles of the other triangle.

So, SSA is not a criterion for congruence of triangles.

Question 8: If two sides of a triangle are of lengths 5 cm and 1. Solution: d Given, the length of two sides of a triangle are 5 cm and 1. Give reason for your answer.

triangles class 9 extra questions with solutions pdf

We know that, two triangles will be congruent by AAS rule, if two angles and the side of one triangle are equal to the two angles and the side of other triangle.

Is the statement true? Solution: No, because in the congruent rule, the two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle i.

Solution: No, because sides must be corresponding sides. Question 5: Is it possible to construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm? Solution: No, it is not possible to construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm because here we see that sum of the lengths of two sides is equal to third side i. As we know that, the sum of any two sides of a triangle is greater than its third side, so given statement is not correct.

Solution: No, we know that two triangles are congruent, if the sides and angles of one triangle are equal to the corresponding side and angles of other triangle. Which side of this triangle is the longest?

Is it true to say that perimeter of the triangle is greater than 2AM? Give reason for your answer? Question Is it possible to construct a triangle with lengths of its sides as 9 cm, 7 cm and 17 cm? Solution: No.

Hence, it contradicts the property that the sum of two sides of a triangle is greater than the third side. Therefore, it is not possible to construct a triangle with given sides. Question Is it possible to construct a triangle with lengths of its sides as 8 cm, 7 cm and 4 cm?

Solution: Yes, because in each case the sum of two sides is greater than the third side. Thinking Process Use the property of a triangle that if two sides are equal then their opposite angles are also equal. Also use the property that side opposite to greater angle is longer. Thinking Process Use the inequality of a triangle i. Further, show the required result. Question 8: In given figure l m and M is the mid-point of a line segment AB.

Show that M is also the mid-point of any line segment CD, having its end points on l and m, respectively. BO is produced to a point M. Question 1: Find all the angles of an equilateral triangle. Question 2: The image of an object placed at a point A before a plane mirror LM is seen at the point B by an observer at D as shown in figure. Prove that the image is as far behind the mirror as the object is in front of the mirror. Thinking Process Firstly, use the property that if two sides of a triangle are equal, then their opposite angles are equal.

Show that AD is the perpendicular bisector of BC. Question Prove that sum of any two sides of a triangle is greater than twice the median with respect to the third side.Students must free download and practice these worksheets to gain more marks in exams.
