Question

in the figure prove that angle A + Angle B + angle C equals to 360 degree...
its very urgent ....
pls anyone solve this

Answer 1

given
in triangle
wkt sum of angles on triangle is 180 degrees so it is and equlateral triangle ; each angle is 60°
we know that angle of linear is 180 degrees
so angle a is 180-60=120
simirally b,C angles also 120 degrees
so angle a+angle b+angle c=360°




HENCE PROVED
I HOPE IT HELPS U

Lets mark the inner angles first,

They are A, B and C

$A = 180^o - a$

$B = 180^o - b$

$C = 180^o - c$

{ They all are linear pairs }

By angle sum property,

$A + B + C = 180^o$

Now lets substitute,

$(180 - a) + (180-b) + (180-c) = 180^o$

Open the brackets,

$180 - a + 180 - b + 180 - c = 180$

$540 - (a+b+c) = 180$

$a + b + c = 540 - 180$

$a + b + c = 360^o$

Hence proved. :)
