GUYS SO BASICALLY FOR EVERYONE WHO IS CONFUSED, in an isosceles triangle, 2 of the sides, and 2 of the angles are equal. AND, if you add all 3 sides of a triangle, you get 180, this guy said the angles at the bases are same. we can take the angle as X, and since there are 2 angles at the base, we make it X+X = 2X so according to what i said above, an equation gets formed 2X + 26 = 180 (2 of the unknown angles at the base + 3rd angle = 180) (180 as all 3 angles added = 180) then you bring 26 to the other side and change the sign so it becomes 2X = 180-26 then 2X = 154 so X = 77

Easy you know that there's 6 triangles acute triangle,right triangle,obtuse triangle, scalene triangle,isosceles triangle and equilateral triangle
GUYS SO BASICALLY FOR EVERYONE WHO IS CONFUSED,

so according to what i said above, an equation gets formed
2X + 26 = 180 (2 of the unknown angles at the base + 3rd angle = 180) (180 as all 3 angles added = 180)
then you bring 26 to the other side and change the sign so it becomes 2X = 180-26 then 2X = 154 so X = 77
Okay easy way :
180-26=154
154 divided by 2
=77 easy
Ok
Thx
oh ez you take 2x and divide two so 180 - 26. 77

Good
👍👍👍
Reason?
Isosceles
Isosceles triangle have two same angle😅
From where did you get 26° ?
It's the question
it's a given, without it we wouldn't be able to make a conclusion
The protractor. DUH!
2 equal sides genius
Nice❤❤
But it's wrong my class teacher told me that this is totally wrong 😢😢😢😢😢😢
Only works for isosceles triangle
How did u get 2?
He just halved it
he got the 2 as there r 2 sides
because the angles on the base need to be equal or congruent so he divided it by 2 to get the same number
You are right I am also confused about w
I don’t need math to prove its a triangle
