The perpendicular distance y of a point from the x-axis is called Ch 7 Maths Class 10 Ex 7.4 its y-coordinate or ordinate. The x and y taken together in order is called coordinte of point denoted by x, y. The coordinate of the points on x-axis are of the form x, 0 and the points on the y-axis are Ch 7 Maths Class 10 Ex 7.4 of the form 0, y. Coordinate of origin is 0, 0. The sign of Ch 7 Maths Class 10 Ex 7.4 x and y-coordinates in each of the quadrant is shown below:.

The distance Ch 7 Maths Class 10 Ex 7.4 Ch 7 Maths Class 10 Ex 7.4 between any two points P x 1 , y 1 and Q x 2 , y Ch 7 Maths Class 10 Ex 7.4 2 in the plane is given by, Also the distance of the point P x 1 , y 1 from the origin is. The coordinates of the point Ch 7 Maths Class 10 Ex 7.4 Ch 7 Maths Class 10 Ex 7.4 P x, y which divides the line segment joining the points A x 1 , Ch Class 10 7.4 Ex 7 Maths y 1 and B x 2 , y 2 internally in the ratio m 1 : 7 Maths Ch 7.4 Ex Class 10 Maths Ex 10 7.4 Ch 7 Class m 2 i. The coordinates of the mid point P of the line segment joining the points A x 1 , y 1 and B x 2 , y 2 is.

Find the distance between the following pairs of points: i 2, 3 , 4, 1 ii -5, 7 , -1, 3 iii a, b , -a, -b Solution: Ex 7. Solution: Ex 7. The sign of x and y-coordinates in each of the quadrant is shown below: Distance Formula The distance between any two points P x 1 , y 1 and Q x 2 , y 2 in the plane is given by, Also the distance of the point P x 1 , y 1 Ch 7 Maths Class 10 Ex 7.4 from the origin is Section Formula The coordinates of the point P x, y which divides the line segment joining the points A x 1 , y 1 Ch 7 Maths Class 10 Ex 7.4 and B x 2 , y 2 internally in the ratio m 1 : m 2 i.

The class X students of a secondary school in Krishinagar have been allotted a rectangular plot of land for their gardening activity. There is a triangular grassy lawn in the plot as shown in the following figure.

The students are to sow seeds of flowering plants on the remaining area of the plot. Also calculate the areas of the triangles in these Byjus Class 8 Maths Chapter 9 Form cases. What Ch 7 Maths Class 10 Ex 7.4 Ch 7 Maths Class 10 Ex 7.4 do you observe? It can be observed that the area of the triangle is Ch 7 Maths Class 10 Ex 7.4 same in both the cases.

Recall Converse of basic proportionality theorem and Theorem 6. Converse of Basic Proportionality Theorem: If a line divides any two sides of a triangle in the same ratio, then the line must be parallel to the third side.

Alternatively, we know that if a line segment in a triangle divides its two sides in the same ratio, then the line segment is parallel to the third side of the triangle[Converse of Basic Proportionality Theorem].

Hence, the ratio between the areas of these two triangles will be the square of the ratio between the sides of these two triangles. A median of a triangle is a line segment joining the vertex to the midpoint of the opposite side, thus Ch 7 Maths Class 10 Ex 7.4 bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid.

Therefore, all these Ch 7 Maths Class 10 Ex 7.4 are representing the same point on the plane i. A rectangle? Or a rhombus?
