    Re: triangle

    really?

    each of these angles is supplementary to each of the interior angles of the triangle.

    so their sum is $3\pi - \pi = 2 \pi$

    Re: triangle

    The sum of the exterior angles of any convex polygon is $360^\circ$

    Re: triangle

    this is not a polygon tho its a triangle . where you add up the angles of the straight lines i get 540 degrees and then i take away 360 cause thats the amount of degrees in a triangle and then im left with 180 .
