Understanding the Distance Formula in Geometry

[Music] hello makawamat in this video lesson we will discuss about about the distance formula okay for example maritime partition plane so only nothing distance from point p to point q okay so it's a point uh point p brother point p to point q coordinating distance minus a point p to point q so on ordered pair from point p negative two and one so point q no man is four and three or four three so enable nothing's negative plus x sub one it's left uh young one nothing is y sub one and then four nut and x sub two and you 3 nothing as y sub 2 or paired in the mana dito young x sub 1 y sub 1 x sub 2 y sub 2 by the ring in class so the distance formula one attend i um distance need to by the way from point p to point q mahuma nothing using the distance formula and that is the square root of the squared of x sub 2 minus x sub 1 plus the squared of y sub 2 minus y sub 1. distance from point p to q or the distance of pq so on nothing so important uh y sub 2 okay so first union another value in x sub 1 that is negative 2 and y sub 1 nothing is one you know x sub 2 nothing is four and y sub to nothing is three so using the formula subtitling okay x sub two num four minus okay x sub one that is negative two since negative two line again nothing open close parenthesis okay and then squared plus the thunderman but nothing y sub to numb three minus uh the value of y sub one that is one so four minus negative two that is four plus two tamar has a negative times negative positive na and that will become six so six square and then three minus one that is two so six squared that is 36 plus uh two squared that is four and 36 plus four that is uh 40 or the square root of 40. so in square root of 40 peripheral and simplify and that is either 2 square root of 10 or equivalent to 6.32 units so ibiza began young distance the pq that is equivalent to 6.32 units another example determine the distance between point a that is 1 6 and point so using the formula so padding at the assignation that our x sub 1 is one our x uh y sub one is six x sub two nominator is five and then x y sub two is negative two so by uh applying the formula the distance formula class subtitling at n your x sub this five minus one plus negative two minus six squared okay pi minus one that is four and negative two minus six that is negative eight four squared is sixteen and negative eight times negative eight that is sixty-four so six square root of 16 plus 64 that is square root of 80 or uh the distance of a b is equal to 4 square root of 5 or equivalent to 8 point 94 units so gangnam nanga meeting distance formula okay now baby jungkook 10 questions okay to test yourself so here are the ten questions okay i hope i know perfect score so pretty uh stop money and vision at all and then 10 questions using the distance formula all right so this here's another answer for number one that is eight units for number two 15 units for number three that is 11.4 units for number four that is 13 units for number five 6.4 units number six 13 units number seven 10.3 units and for number eight 11.66 units and for number nine that is 13.6 units and for number 10 12.81 units okay class 10 congratulations in advance okay and to find the distance formula between nundella one uh and point nathan now in class if you want to share your score so pretty new comments so comment section and video lesson at all thank you for watching this video i hope you learned something don't forget to like subscribe and hit the bell button put updated ko for more video tutorial this is your guide in learning your mod lesson your walmart channel
