The figure shows three exterior angles of triangle ABC. Show that the measure of angle 1 plus the measure of angle 2 plus the me

ivolga24 [154]

Step-by-step explanation:

Let the angle near point A be $A$ .

Let the angle near point B be $B$ .

Let the angle near point C be $C$ .

Let the external angle near point A be $extA$ .

Let the external angle near point B be $extB$ .

Let the external angle near point C be $extC$ .

According to exterior angle property,exterior angle of an angle is the sum of other two angles.

So,

$extA=B+C\\extB=A+C\\extC=A+B$

According to angle sum property,the sum of angles in the triangle add to $180$

$extA+extB+extC=B+C+A+C+A+B=2(A+B+C)=2\times 180=360^{0}$
