Let x be the angle that's next to angle b and INSIDE the triangle.

So, we know that x + b = 180

Or we can write

x = 180 - bLet y be the angle that's next to angle c and INSIDE the triangle.

So, we know that y + c = 180

Or we can write

y = 180 - cSince angles a, x and y are the 3 angles in the triangle, we can write: a +

x +

y = 180

Now replace x and y to get: a +

(180 - b) +

(180 - c) = 180

Simplify to get: a - b - c + 360 = 180

Rearrange to get a + 180 = b + c

AHA, this is EXACTLY what we are comparing.

Answer:

Cheers,

Brent
