It’s actually common sense when you think about it. In order for a line to be perpendicular they have to be going at the same rate but at different directions, that is how we get the 90 degree on all angles. So multiplying both numbers should lead to -1, if one number is positive then it’s perpendicular should be negative and vice versa, if the y value goes up twice like a slope that is 2 then it’s opposite should be x moving twice and y only once which is the 1/2 slope and vice versa.
@@DianaLlovitmacam08 You are absolutely right mate. However, not everyone has an intuitive mathematical thought or common sense like that of yours, and unfortunately, I fall into that category. Hence, my motive was to only bring the channel's attention to the need for the explanation, as it would help others like myself.
@Sarath Nambiar I see where you are coming from and I agree with you. They really should explain it so my comment wouldn’t be necessary. Have a nice day!
How did you find the coordinates of CD? You said the perpendicular line will look like that but how did you find exactly how the perpendicular line will look like?

Does bisector mean that the line will intersect the original line at exactly the midpoint? Bisect only means to cut in two, it doesnt mean two equal halfs. Or in this case does it mean 2 equal halfs? In order for something to pass through the midpoint it must "Cut" the original line equally in two.
Yes, a bisector will cut something in half (exactly two congruent pieces). It is not necessary that the bisector is itself cut in half, however. In the example that she uses, the line segment AB is bisected. It is not possible to bisect an infinite line as there is no way to locate the midpoint though it is always possible to find a perpendicular line.
Mid point of line AB are (2,1) and as per previous video slope of line mid point m = -y/x. In this case slope of line AB should be m = -1/2? but it is derived as -2?
if you have slop -2 and if we will apply your trick ( which you have been explained in your last 5th video - If we have Mid point so for slop we can apply directly formula slop = (-y)/(x) ) - with this trick i will get Mid point (1,2) not (2,1). HOW is that possible then? .
It doesn't matter. The order is arbitrary. You will either end up with -2/1 or 2/-1. The final answer for the slope of the original line segment is -2. All that matters is that whichever y you use first, you must use that x first, also.
Think of it this way: perpendicular is a kind of "opposite" so, your rise becomes run and your run becomes rise. Also, one will have to go up hill and the other down. In the example used, -2/1 * 1/2. No matter what perpendicular slopes you have, the product will be -1.
It is observable that the slopes of 2 perpendicular lines are always negetive reciprocals of each other. And when you multiply negetive reciprocals the product is -1. For example, 2 * (-1/2) = -1 , 5 * (-1/5) = -1 You can check it on a graph with 2 perpendicular lines too. The product of both slopes will always be -1.
If two non-vertical lines are perpendicular, the slope of one is negative reciprocal of the slope of other

THANK YOU 😭😭💖💖💖
I really like your explanation thanku so much may u reach the point of excellence always aameen
Initially, I saw one video on geometry topic. Now I can't stop my hand to search a particular topic over your videos.
Appreciate the effort behind the video. Love you guys. 😍😍😍
These videos are splendid...really... It helped me a lot
Mam i will give you one short tip i think that help.

This Indian woman explaining geometry in English is so much nicer to listen to and absorb than an American male speaker for some reason

@Don't Memorise,
How about the product of slopes of x and y axes? Their product is not -1 even though they are perpendicular to each other.
Its good persist with the effort ,that's what l can tell u
Amazing video 🙏
Thank you so much! Very clear and simple. Love ur voice btw 😘
Excellent
Thanks a lot for your perfect videos 😍♥️♥️♥️♥️
Good

Very good👏🎬👏🎬👏🎬👏🎬👏
What an irony, the channel's name is "don't memorise", yet they ask us to memorise m1*m2 = -1 and not explain how we arrive at such a conclusion.

I don't understand m3*m4 = -1
could you tell me how its become -1
Just use the transformation theory - > rotation 90 degrees

Diy Crafts maker you are sooo pretty ;*
Does bisector mean that the line will intersect the original line at exactly the midpoint? Bisect only means to cut in two, it doesnt mean two equal halfs. Or in this case does it mean 2 equal halfs? In order for something to pass through the midpoint it must "Cut" the original line equally in two.
Christina Rosette it's not relevant whether or not it cuts the line in exact halves. That is irrelevant to finding the answer
Yes, a bisector will cut something in half (exactly two congruent pieces). It is not necessary that the bisector is itself cut in half, however. In the example that she uses, the line segment AB is bisected. It is not possible to bisect an infinite line as there is no way to locate the midpoint though it is always possible to find a perpendicular line.

Hi
This is amaizing.
Thank you so much I understand all the topic

previews question was - P ( 2, -3 ) is the mid point then slop "m" would be 3/2 answer because a/c to formula slop m= (-y)/x.

Say it with me per-pen-dicular it’s not fucking hard
I'm confused as to why you do Y1-Y2/X1-X2 instead Y2-Y1/X2-X1?
It doesn't matter. The order is arbitrary. You will either end up with -2/1 or 2/-1. The final answer for the slope of the original line segment is -2. All that matters is that whichever y you use first, you must use that x first, also.
Why does the product of slope of two mutually perpendicular lines is -1 ?
Think of it this way: perpendicular is a kind of "opposite" so, your rise becomes run and your run becomes rise. Also, one will have to go up hill and the other down. In the example used, -2/1 * 1/2. No matter what perpendicular slopes you have, the product will be -1.

What is the meaning of slope
picks has changed his life at night time
Jayhawks should be an awesome game but not like it was just fun
So nice video but in Hindi
The angle between two lines in180° .both lines are parallel or perpendicular
They are parallel. It is the same as for lines coinciding which have 0 angle in between them
They're perpendicular as their angle is 180° which is a straight angle. It will be easier for you to understand, if you just draw them.
Not good😡
ok gud for u

It's so hard to math
What is -1
No entiendo :,)
:
CAN SOMONE HELP I DONT UNDERSTAND
.....????
How did she get 0 at the end?
1=1/2×2+b
1/2×2=1
So 1=1+b
b=1-1=0
Tnx for nothing😐👍
Please maim give answer
wut?
How come -1-3 is -2 it's should be -4
I don’t understand why M3 times M4 equals -1.
We dont question math, math quesions us
@@senseimoo366 LOL
It is observable that the slopes of 2 perpendicular lines are always negetive reciprocals of each other. And when you multiply negetive reciprocals the product is -1.
For example,
2 * (-1/2) = -1 ,
5 * (-1/5) = -1
You can check it on a graph with 2 perpendicular lines too. The product of both slopes will always be -1.
