In the given triangle ABC AB BC and CA represent three sides A B and C are the three vertices and ABC BCA and CAB are three interior angles of ABC Theorem 1 Angle sum property of triangle states that the sum of interior angles of a triangle is 180 176 Proof Consider a ABC as shown in the figure below Let s calculate the sum of the interior angles of a triangle using the sum of interior angles formula S 180 n 2 176 where n is the number of sides in a polygon Here n is 3 as the triangle has 3 sides
Sum of all the interior angles of the triangle is 180 176 That is These are the following steps involved to prove angle sum property theorem Step 1 Draw a line AB through the vertex P and parallel to the side QR of a triangle PQR Step 2 Now Step 3 Step 4 Step 5 Substituting respectively The angle sum property of a triangle states that the sum of the angles of a triangle is equal to 180 186 A triangle has three sides and three angles one at each vertex Whether a triangle is an acute obtuse or a right triangle the sum of its interior angles is always 180 186
