straight-line method

The straight path joining two points A and B is called a line segment ..

A boy is playing with a ring of diameter 80 cm. It rolled down from his hands and made 12 revolutions while moving in a straight line and then came to stop. The boy normally covers a distance of 0.4 m in one step. How many steps he has to move to collect the ring? [Take π = 3..

Equation of the line passing through the intersection of two lines - Let the lines be Let P (h,k) be the point of intersection of L 1 = 0 and L 2 = 0. Now consider the following equations, (v) (vi) This equation is a first degree in x and y and hence this represents a ..

Which of the following statements is correct? I. There are finite number of staright lines passing through any two points on a plane, in plane Euclidean Geometry. II.There are finite number of great circles passing through any two non-polar points on a sphere, in spherical seometry. III. ..

0.4226x = 5.774 = 13.7 m height of the tower = 13.7 m. 2 n d Method (By formula ): In prove..

Single plant with desirable characters from genetically divergent population is selected and it is selfed. In second generation, the seeds of individual selfed plants are sown in separate lines and further selections are made. Pure line selection consolidates a particular chara..

Introduction - Recall that if two straight lines are not parallel, they meet at a point when produced. Observe lines l and m which meet at a point (O). In the diagram, l and m are called intersecting lines. O is called the point of intersection. Similarly two..

Let AB be any straight line. OP = p is a perpendicular drawn to AB from the origin. Let the co-ordinates of P be (x,y). From right-angled triangle OAP, Again from right-angled triangle OAP..

Then (x 1 , y 1 ) lies on both (i) and (ii). Solving for x 1 and y 1 by the method of cross multiplication, we obtain ..

A particle is moving along a straight line according to the law S = 3 ut - 5 at 2 where a > 0. Find the greatest and least velocities of the particle. => 3 u , 0 or 0, u or u , - u or - u , u..
