Question

what is the formula of distance in maths only girls can answer this ?

Answer 1

The formulae for distance between two points is as follows

Let the two points be A (x1,y1) and B (x2,y2)

Draw two perpendiculars AP and BQ from point A and B respectively.

From A a perpendicular AR is drawn onto BQ

Then OP will be x1 and OQ will be x2

The distance between P and Q will be given by OQ-OP=x2-x1

QR=y1 and QB is y2

Then the distance between R an B will be QB-QR=y2-y1

When we confided the right angled triangle ABR

By Pythagorean theorem we get AB²=AR²+RB²

AB²=(x2-x1)²+(y2-y1)²

AB=√(x2-x1)²+(y2-y1)²
