In a triangle ABC , If AB , BC , and CA are produced in order to forming exterior angle
which is angle ACD , angle BAE and angle CBF.

/_ ACD = /_ A + /_ B

/_BAE = /_ B + /_ C

/_CBF = /_ C + /_ A

SO IN A TRIANGLE,

1 . The exterior angle is equal to the sum of the interior opposite angles.

2. Exterior angle of a triangle is greater than either of the two interior opposite angles.

3. Sum of the all the three angles of a triangle is 180°
