How many formulas are there in co ordinate geometry class 10?
Ans: There are three important formulas in coordinate geometry studied in Class 10.
What is coordinate formula?
(1) Distance Formula: To Calculate Distance Between Two Points: Let the two points be A and B, having coordinates to be (x_1,y_1) and (x_2,y_2) respectively. Thus, the distance between two points is- distance = \sqrt {( {x_1 – x_2 } )^2 + ( {y_1 – y_2 } )^2 }
How is coordinate geometry applied in a PDF?
The text file or PDF file which we open is itself an example of coordinate plane. In these, the words or images are written or modified with the use of coordinate geometry. Any PDF file, which contains text, images and different shapes, are placed according to the 2-dimentional coordinate (x, y) system.

What is the distance formula in coordinate geometry?
Distance can be calculated using the formula derived from Pythagoras theorem. In coordinate geometry, the distance formula is √[(x2 – x1)^2 + (y2 – y1)^2].
How do you find the coordinate formula?
1. Distance between two points P(x1,y1) and Q(x2,y2) is given by: d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 {Distance formula} 2. Distance of a point P(x, y) from the origin is given by d(0,P) = √ x2 + y2.
What is the formula of triangle in coordinate geometry?
The formula of area of triangle formula in coordinate geometry the area of triangle in coordinate geometry is: A = (1/2) |x1 1 (y2 2 − y3 3 ) + x2 2 (y3 3 − y1 1 ) + x3 3 (y1 1 − y2 2 )|, where (x1 1 ,y1 1 ),(x2 2 ,y2 2 ), and (x3 3 ,y3 3 ) are the coordinates of vertices of triangle.
Who is the father of coordinate geometry?
René Descartes
The invention of Cartesian coordinates in the 17th century by René Descartes (Latinized name: Cartesius) revolutionized mathematics by providing the first systematic link between Euclidean geometry and algebra.
What does formula mean in geometry?
A formula is a mathematical rule or relationship that uses letters to represent amounts which can be changed – these are called variables. The plural of formula is formulae or formulas.
What are the formulas for distance?
To solve for distance use the formula for distance d = st, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t.
