In Figure,the side BC of ABC is produced to form ray BD as shown.Ray CE is drawn parallel to BA .Show directly,without using the angle sum property of a triangle that ACD=/_A+/_b and deduced that /_A+/_B+/_C=180^(0).

In Figure,the side BC of hat grad ABC is produced to form ray BD as shown.Ray CE is drawn parallel to BA. Show directly,without using the angle sum property of a triangle that /_ACD=/_A+/_B and deduced that /_A+/_B+/_C=180^(@).

THEOREM (Exterior Angle Property of a Triangle): If a side of a triangle is produced the exterior angle so formed is equal to the sum of two interior opposite angles.
